Ingredient Restrictions Update

✅ Changes Made

1. Strict Ingredient Usage

• Recipes now ONLY use detected ingredients (when ingredients are scanned)
• No random ingredients will be added
• Very clear and explicit instructions in the AI prompt

2. Flexible Combination

• Recipes don't need to use all detected ingredients
• Each of the 3 recipes uses a different combination of detected ingredients
• More variety in recipe suggestions

3. Common Pantry Items Exception

Always allowed even if not detected:

• Salt
• Pepper / Black pepper
• Olive oil / Vegetable oil / Cooking oil
• Garlic / Onion
• Garlic powder / Onion powder
• Basic seasonings / Herbs / Common spices

4. Updated UI

• Clear explanation of ingredient rules in the Recipe Generator tab
• Shows what items are always allowed
• Explains that recipes only use detected ingredients

📋 How It Works

When Ingredients Are Detected:

Detected: ["chicken", "tomatoes", "pasta", "cheese"]

Recipe 1: Uses chicken + tomatoes + salt + pepper + oil
Recipe 2: Uses pasta + cheese + garlic + salt + pepper  
Recipe 3: Uses chicken + pasta + tomatoes + oil + seasonings

❌ Won't add: potatoes, rice, or any other non-detected items
✅ Will add: salt, pepper, oil, garlic (common pantry items)

When No Ingredients Are Detected:

• Falls back to flexible recipe generation
• Uses common pantry items
• Works as before

🔍 Code Changes

Prompt Structure:

1. STRICT INGREDIENT REQUIREMENTS section (when ingredients detected)

   • Lists detected ingredients
   • Lists allowed common pantry items
   • Explicitly forbids other ingredients
   • Emphasized multiple times in the prompt

2. REMINDER section

   • Reinforces the restrictions
   • Makes it very clear what can and cannot be used

UI Updates:

• Added ingredient rules explanation in description box
• Added "With Detected Ingredients" section explaining the behavior
• Clear messaging about common pantry items

🎯 Example

Input:

• Detected ingredients: "chicken", "tomatoes", "rice"
• Cuisine: "Italian"

Output:

• Recipe 1: Chicken and Tomato Risotto (uses chicken + tomatoes + rice + salt + pepper + oil + garlic)
• Recipe 2: Italian Chicken with Tomatoes (uses chicken + tomatoes + salt + pepper + herbs + oil)
• Recipe 3: Tomato Rice Bowl (uses tomatoes + rice + garlic + oil + seasonings)

Key Points:

• ✅ Only uses detected items + common pantry items
• ✅ Each recipe has different combinations
• ✅ No random ingredients added
• ✅ Still practical and delicious!
