+## 🧈 Perfect Ghee: A Scientific, Step-by-Step Guide
+
+### 🔬 What Is Ghee?
+
+Ghee is **butterfat** with all water and milk solids (proteins & sugars like lactose) removed. This makes it:
+
+* Shelf-stable
+* Lactose- and casein-free
+* Suitable for high-heat cooking (smoke point \~480°F / 250°C)
+
+---
+
+### 🧪 Science Principles
+
+* **Butter = \~80% fat + \~18% water + \~2% milk solids**
+* Heating evaporates water and causes the **Maillard reaction** in milk solids (nutty flavor).
+* **Low & slow heating** avoids burning and ensures even clarification.
+* Browning of milk solids = richer flavor; burning = bitterness.
+
+---
+
+### 🛒 Ingredients
+
+* **High-quality unsalted butter**, preferably:
+
+  * **Grass-fed (e.g., Kerrygold)** for better CLA and vitamin K2 content.
+  * **Cultured butter** adds extra complexity via fermentation notes.
+
+---
+
+### 🍳 Equipment
+
+* Heavy-bottomed saucepan (prevents hot spots).
+* Fine mesh strainer or cheesecloth.
+* Heat-safe glass jar with tight lid.
+
+---
+
+### 🔥 Cooking Process (Slow Clarification Method)
+
+1. **Cut butter into chunks** – faster, even melting.
+2. **Melt gently** over **low heat** in the pan. Don't stir.
+3. **Simmer gently** – tiny bubbles should form. Water is evaporating now.
+4. **Skim off foam** (first layer of denatured whey proteins).
+5. **Let milk solids sink** – you'll see golden liquid on top, milk solids at the bottom.
+6. **Watch color** – when solids at the bottom are light brown and liquid is clear and golden, it's ready.
+
+   * Optional: let it go slightly longer for nuttier flavor (careful not to burn).
+7. **Remove from heat immediately.**
+8. **Strain through cheesecloth** into a clean, dry jar.
+
+---
+
+### 🌡️ Temperature Tips
+
+Use a thermometer for precision:
+
+* Water evaporates: **212°F (100°C)**
+* Milk solids brown: **250°F–285°F (120–140°C)**
+* Burn risk: **>300°F (150°C)**
+
+Stay between **260–280°F** for best flavor development without scorching.
+
+---
+
+### 🧊 Storage
+
+* Let cool, seal jar.
+* **Room temp:** 3+ months
+* **Fridge:** 1 year+
+* Always use clean utensils to avoid contamination.
+
+---
+
+### 🧠 Pro Tips
+
+* **Brown butter = almost ghee**, but not strained.
+* **Add curry leaves or bay leaf during cooking** for infused ghee (strain them out later).
+* **Don't stir** once melted — it can remix the milk solids.
+* For ultra-pure ghee: **double strain** through cheesecloth or nut milk bag.
