While not ideal, you *can* make a layered biryani in a rice cooker, but it requires careful monitoring and adjustments to prevent burning or uneven cooking. The key is to layer pre-cooked ingredients and use the 'cook' setting sparingly, switching to 'warm' to steam the biryani.
Making biryani in a rice cooker is a bit of a workaround, as rice cookers are designed for simple rice cooking, not the complex layering and steaming required for a good biryani. However, it's possible with some adjustments. Here's a step-by-step technique:
Prepare Your Ingredients: Fully cook your meat or vegetables in a separate pan with your biryani spices. Parboil your rice until it's about 70% cooked. It should still be firm.
Layering: Lightly grease the bottom of the rice cooker. Add a layer of the parboiled rice, followed by a layer of your cooked meat/vegetable mixture. Repeat these layers, ending with a layer of rice on top.
Adding Moisture: Sprinkle a few tablespoons of milk or saffron-infused water over the top layer of rice. This will help with steaming and add flavor.
Cooking: Close the rice cooker lid and set it to the 'cook' setting. Monitor it closely. As soon as you see steam escaping vigorously or smell the rice starting to burn (a common issue), immediately switch the rice cooker to the 'warm' setting. This will allow the biryani to steam gently without burning.
Steaming: Let the biryani steam on the 'warm' setting for about 15-20 minutes, or until the rice is fully cooked and the flavors have melded together.
Fluff and Serve: Gently fluff the biryani with a fork before serving. Be careful not to mash the rice.
To prevent burning, place a heat-diffusing mat or a thin metal plate at the bottom of the rice cooker before layering. This will help distribute the heat more evenly and reduce the risk of scorching.
