**Misti Doi** (sweet yogurt) is a popular Bengali dessert made by fermenting milk and sweetening it with sugar or jaggery. It has a rich, creamy texture and a caramelized flavor. Here’s how you can make it at home:
### Ingredients:
- **Full-fat milk** – 1 liter
- **Sugar** – 1/2 cup (adjust to taste)
- **Jaggery (optional)** – 2-3 tablespoons for a traditional flavor
- **Yogurt** – 2 tablespoons (plain, unflavored, for culture)
### Instructions:
#### Step 1: Boiling the Milk
1. In a heavy-bottomed pan, heat the milk and bring it to a boil. Once it boils, reduce the heat to low and simmer the milk until it reduces to about 75% of its original quantity. Stir occasionally to prevent the milk from burning at the bottom.
#### Step 2: Caramelizing the Sugar
2. In a separate small pan, melt the sugar over low heat until it turns golden brown (caramelized). Be careful not to burn it.
3. Once caramelized, carefully add the caramelized sugar to the simmering milk and mix well. The caramel will give the misti doi its signature light brown color and a rich flavor.
#### Step 3: Adding Jaggery (Optional)
4. If using jaggery, add it to the milk after the caramelized sugar has blended well. Stir continuously until the jaggery melts completely. Remove the pan from the heat and let the milk cool until it is lukewarm.
#### Step 4: Fermentation
5. Once the milk is lukewarm (not hot), add the yogurt and mix thoroughly. The yogurt acts as the starter culture to ferment the milk.
6. Pour the mixture into earthen pots or any container of your choice. The earthen pots are preferred as they absorb moisture, making the yogurt thicker.
#### Step 5: Setting the Misti Doi
7. Cover the pots with a lid or a cloth and let the yogurt set in a warm place for 8-10 hours or overnight, depending on the ambient temperature. In cooler climates, it might take a bit longer.
8. Once the misti doi is set, refrigerate it for a few hours to chill before serving.
### Serving:
Serve chilled misti doi as a dessert after meals. It’s best enjoyed on its own or with a garnish of chopped nuts if desired.
Enjoy the creamy, sweet delight of homemade misti doi!
