+# 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!
