🍽️ Recipe Discovery App

Here’s the secret to building smart AI applications: guided user experiences + specialized prompts = powerful apps.

Want a recipe discovery app? Skip the complex chat interface. Build a multi-step form that guides users through meal selection, then use AI to return perfectly formatted recipe cards with step-by-step instructions.

This lesson teaches you: How to create guided AI experiences that feel like premium apps. You’ll build a recipe discovery platform that rivals food apps costing millions - using forms, structured data, and smart prompting.

Building on: This transforms your AI foundation into a specialized application with visual interfaces, structured responses, and smooth user flows.

🎯 From Chat to Guided Experience: The App Pattern

Here’s what most people build first:

❌ Generic chat interface
❌ Users typing random questions
❌ Inconsistent AI responses
❌ Hard to use on mobile

Here’s what we’ll build instead:

✅ Guided meal selection forms
✅ Structured AI recipe responses
✅ Visual recipe cards and galleries
✅ Step-by-step cooking slideshows

Watch this transformation happen:

Traditional approach: User types “give me a dinner recipe” → AI gives random text wall

Our approach: User selects “Dinner” → “Italian” → “30 minutes” → AI returns 10 beautiful recipe cards with photos, ingredients, and difficulty ratings

The result: A recipe discovery experience that feels like a premium food app, not a chatbot.

🛠️ Step 1: Build Your Recipe Discovery API (Backend First)

We’ll create two specialized endpoints: one for getting recipe suggestions, and another for detailed cooking instructions. This replaces generic chat with structured recipe data.

Add these endpoints to your index.js:

// 🍽️ RECIPE DISCOVERY: Get curated recipe suggestions
app.post("/api/recipes/discover", async (req, res) => {
  try {
    const {
      mealType,
      cuisine = null,
      cookingTime = null,
      difficulty = 'any',
      dietary = null
    } = req.body;

    if (!mealType) {
      return res.status(400).json({ error: "Meal type is required" });
    }

    const recipeExpert = `You are a world-class culinary AI that creates perfect recipe recommendations. You specialize in understanding what people want to eat and suggesting exactly the right dishes.

YOUR MISSION: Return exactly 10 recipe suggestions as a JSON array. Each recipe must be complete and appealing.

YOUR EXPERTISE:
- Perfect recipe matching for any meal type and cuisine
- Accurate cooking times and difficulty levels
- Beautiful, appetizing descriptions that make people want to cook
- Smart dietary accommodations and substitutions
- Realistic ingredient lists that people can actually find

RESPONSE FORMAT (JSON only, no markdown):
[
  {
    "id": 1,
    "name": "Recipe Name",
    "description": "One appetizing sentence about this dish",
    "prepTime": "15 minutes",
    "cookTime": "25 minutes",
    "totalTime": "40 minutes",
    "difficulty": "Easy",
    "servings": 4,
    "cuisine": "Italian",
    "mainIngredients": ["chicken", "pasta", "tomatoes"],
    "tags": ["comfort-food", "weeknight"],
    "calories": 420
  }
]

REQUEST CONTEXT:
- Meal type: ${mealType}
${cuisine ? `- Cuisine preference: ${cuisine}` : ''}
${cookingTime ? `- Time available: ${cookingTime}` : ''}
${difficulty !== 'any' ? `- Difficulty level: ${difficulty}` : ''}
${dietary ? `- Dietary requirements: ${dietary}` : ''}

IMPORTANT: Return only valid JSON array with exactly 10 recipes. No explanations, no markdown formatting.`;

    console.log(`🔍 Discovering ${mealType} recipes...`);

    const response = await openai.chat.completions.create({
      model: "gpt-4o-mini",
      messages: [{ role: "user", content: recipeExpert }],
      temperature: 0.8
    });

    const recipesJson = response.choices[0].message.content;
    const recipes = JSON.parse(recipesJson);

    res.json({ recipes });

  } catch (error) {
    console.error("Recipe discovery error:", error);
    res.status(500).json({ error: "Failed to discover recipes" });
  }
});

// 📜 RECIPE INSTRUCTIONS: Get detailed cooking steps
app.post("/api/recipes/instructions", async (req, res) => {
  try {
    const { recipeId, recipeName } = req.body;

    if (!recipeName) {
      return res.status(400).json({ error: "Recipe name is required" });
    }

    const instructionExpert = `You are Chef Isabella, a master cooking instructor who creates the clearest, most helpful recipe instructions in the world.

YOUR MISSION: Create detailed cooking instructions for "${recipeName}" as a JSON object with step-by-step guidance.

YOUR TEACHING STYLE:
- Crystal clear, numbered steps that anyone can follow
- Specific techniques, temperatures, and timing
- Pro tips that make the difference between good and great
- Visual cues so cooks know what to look for
- Encouraging tone that builds confidence

RESPONSE FORMAT (JSON only):
{
  "recipeName": "${recipeName}",
  "ingredients": [
    {
      "item": "ingredient name",
      "amount": "2 cups",
      "preparation": "diced"
    }
  ],
  "equipment": ["large skillet", "mixing bowl"],
  "steps": [
    {
      "stepNumber": 1,
      "instruction": "Detailed step with timing and technique",
      "tip": "Chef's pro tip for this step",
      "visualCue": "What it should look like when done"
    }
  ],
  "servingTips": "How to serve and present this dish",
  "variations": ["Alternative ingredients or methods"]
}

IMPORTANT: Return only valid JSON. Make instructions detailed but easy to follow.`;

    console.log(`📋 Creating instructions for ${recipeName}...`);

    const response = await openai.chat.completions.create({
      model: "gpt-4o-mini",
      messages: [{ role: "user", content: instructionExpert }],
      temperature: 0.7
    });

    const instructionsJson = response.choices[0].message.content;
    const instructions = JSON.parse(instructionsJson);

    res.json(instructions);

  } catch (error) {
    console.error("Recipe instructions error:", error);
    res.status(500).json({ error: "Failed to get recipe instructions" });
  }
});

What makes this different from chat:

• Structured responses - JSON data instead of text streams
• Specific purposes - Discovery vs. detailed instructions
• Predictable formats - Apps can build beautiful UIs around consistent data
• No conversation needed - Users get exactly what they want immediately

📱 Step 2: Build Your Recipe Discovery Interface (Frontend Magic)

Now we’ll create a guided experience that feels like a premium food app. No chat boxes - just beautiful forms, recipe cards, and step-by-step cooking guides.

Save your existing chat first, then build the new interface:

2A: Preserve Your Chat Component

# Save your current work
cp src/App.jsx src/Chat.jsx

Your existing chat is valuable - keep it as Chat.jsx for future projects. This preserves your streaming, memory management, and localStorage work.

2B: Create Your Recipe Discovery App

Replace your src/App.jsx with this multi-step recipe discovery experience:

// src/App.jsx - Recipe Discovery App: Multi-step AI recipe finder

    cuisine: null,
    cookingTime: null,
    difficulty: 'any'
  })
  const [recipes, setRecipes] = useState([])
  const [selectedRecipe, setSelectedRecipe] = useState(null)
  const [recipeInstructions, setRecipeInstructions] = useState(null)
  const [currentInstructionStep, setCurrentInstructionStep] = useState(0)
  const [isLoading, setIsLoading] = useState(false)

    { id: 'lunch', label: 'Lunch', emoji: '☀️', desc: 'Midday fuel' },
    { id: 'dinner', label: 'Dinner', emoji: '🌙', desc: 'Evening feast' }
  ]

  // Step 2: Cuisine Selection
  const cuisineOptions = [
    { id: 'italian', label: 'Italian', emoji: '🍝', desc: 'Classic comfort' },
    { id: 'asian', label: 'Asian', emoji: '🥢', desc: 'Bold flavors' },

      })

      if (!response.ok) throw new Error('Failed to discover recipes')

      const data = await response.json()
      setRecipes(data.recipes)

    } finally {
      setIsLoading(false)
    }
  }

  // Get detailed recipe instructions
  const getRecipeInstructions = async (recipe) => {
    setIsLoading(true)
    setSelectedRecipe(recipe)
    try {
      const response = await fetch('http://localhost:8000/api/recipes/instructions', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
          recipeId: recipe.id,
          recipeName: recipe.name
        })
      })

      if (!response.ok) throw new Error('Failed to get instructions')

      const instructions = await response.json()
      setRecipeInstructions(instructions)
      setCurrentInstructionStep(0)

What makes this completely different from chat:

🚀 Guided Multi-Step Experience

• No typing required - Visual selection cards for every choice
• Progressive disclosure - One decision at a time, building user’s preferences
• Step indicator - Users always know where they are in the process
• Back navigation - Easy to change previous choices

🎯 Structured Data & Beautiful Cards

• Recipe cards - Beautiful grid layout with photos, timing, and difficulty
• JSON responses - Predictable data format that UI can display consistently
• Visual hierarchy - Clear information design instead of text walls
• Interactive elements - Buttons, cards, and visual feedback everywhere

📱 App-Like Functionality

• Step-by-step cooking slideshow - Each instruction on its own screen
• Progress tracking - Visual progress bar during cooking
• Professional presentation - Feels like a premium recipe app, not a chatbot
• Mobile-first design - Perfect for kitchen use on phones and tablets

This shows the power of structured AI responses combined with thoughtful UI design. Instead of “chat with AI,” you’ve built “AI-powered recipe discovery app.”

🧪 Step 3: Test Your Recipe Discovery App

Let’s see how your multi-step interface creates a completely different experience from traditional chat:

Start your servers:

Backend:

cd openai-backend
npm run dev

Frontend:

cd openai-frontend
npm run dev

Experience the guided recipe discovery:

Phase 1: Multi-Step Selection Flow

1. Visit http://localhost:5173
   • See the blue/purple theme with step indicator
   • Click "Dinner" to start the meal selection
   • Notice how it automatically moves to cuisine selection
   • Try "Italian" and observe the smooth transitions
   • Select "30 minutes" cooking time and "Medium" difficulty
   • Watch the "Discover Recipes" button activate

Phase 2: Recipe Cards & AI-Generated Data

2. Click "Discover Recipes" and watch:
   • Loading animation with "Finding recipes..." text
   • Beautiful grid of 10 recipe cards appears
   • Each card shows: name, description, timing, servings, calories
   • Ingredient tags and difficulty badges
   • Professional layout that looks like a real food app

3. Examine the recipe cards:
   • "Creamy Mushroom Risotto" - 35 minutes, Medium, 4 servings, 380 cal
   • "Chicken Parmigiana" - 25 minutes, Medium, 4 servings, 520 cal
   • "Spaghetti Carbonara" - 20 minutes, Medium, 4 servings, 450 cal
   • Notice how AI creates consistent, realistic recipe data

Phase 3: Step-by-Step Cooking Slideshow

4. Click "Cook This Recipe" on any card:
   • New interface loads with green cooking theme
   • Progress bar shows "Step 1 of 8" with visual progress
   • Large step numbers and clear instructions
   • "Chef's Tips" in yellow boxes with professional advice
   • "Look for" sections in blue boxes with visual cues

5. Navigate through the cooking steps:
   • Click "Next Step" to advance through each instruction
   • Try "Previous" to go back and review steps
   • Notice the completion celebration when finished
   • "Find Another Recipe" button resets the entire flow

Phase 4: Compare with Chat Experience

6. Open your saved Chat.jsx in another tab:
   • Ask: "Give me an Italian dinner recipe"
   • Notice the text-wall response vs beautiful cards
   • See generic AI assistant vs specialized app experience
   • Compare typing/chatting vs clicking/selecting

What makes this revolutionary:

• Zero typing required - Pure visual interaction
• Structured AI responses - JSON data creates beautiful UIs
• Progressive experience - Each step builds on the previous
• Mobile-perfect - Touch-friendly cards and buttons
• App-like feel - No one would guess this is AI-powered

🔧 Common Issues & Solutions

❌ “Recipe discovery returns empty or broken JSON”

• ✅ Check backend console logs for JSON parsing errors
• ✅ Verify the OpenAI model is returning valid JSON format
• ✅ Test the /api/recipes/discover endpoint directly with curl
• ✅ Make sure your prompt specifically requests “JSON only, no markdown”

❌ “Step selection cards don’t advance to next screen”

• ✅ Verify selections state is updating correctly in browser dev tools
• ✅ Check that currentStep state changes when buttons are clicked
• ✅ Ensure all meal types, cuisines, and time options have correct IDs

❌ “Recipe instructions slideshow doesn’t load”

• ✅ Confirm /api/recipes/instructions endpoint returns valid JSON
• ✅ Check that recipe name is being passed correctly to the backend
• ✅ Verify recipeInstructions state is populated before rendering

❌ “App looks broken on mobile devices”

• ✅ Make sure you’re using responsive Tailwind classes (md:, lg:)
• ✅ Test the card grids collapse properly on smaller screens
• ✅ Verify touch interactions work on recipe cards and navigation buttons

❌ “Backend API errors or 500 responses”

• ✅ Check that your OpenAI API key is set correctly
• ✅ Verify you’re using gpt-4o-mini model (not streaming endpoint)
• ✅ Ensure JSON.parse() doesn’t fail on malformed AI responses
