For split chickpeas (chana dal), typically 2-3 whistles on medium heat in a pressure cooker are sufficient to cook them properly. The exact number can vary based on the cooker and the dal's age.
Cooking chana dal in a pressure cooker is a common and efficient method. The number of whistles needed depends on several factors, including the size and type of your pressure cooker, the quality and age of the chana dal, and your desired consistency. Here's a general guideline:
Soaking: Soak the chana dal for at least 30 minutes to an hour before cooking. This helps soften the dal and reduces cooking time.
Water Ratio: Use a water-to-dal ratio of approximately 2:1 or 3:1. Too little water can cause burning, while too much can result in a watery dal.
First Whistle: Cook on high heat until the first whistle. This builds up the pressure quickly.
Subsequent Whistles: Reduce the heat to medium and allow 1-2 more whistles. This ensures the dal cooks through without burning.
Natural Pressure Release: Allow the pressure to release naturally. This prevents the dal from splattering and ensures even cooking. If you're in a hurry, you can carefully release the pressure manually, but be cautious of hot steam.
Check Consistency: After the pressure is released, check the consistency of the dal. It should be soft but not mushy. If it's still firm, you can pressure cook for another whistle or simmer on the stovetop until it reaches the desired consistency.
Adding a pinch of turmeric powder and a teaspoon of oil or ghee while pressure cooking can enhance the flavor and prevent the dal from foaming excessively, which can clog the pressure cooker valve.
