Punjabi sweet lassi recipe - Punjabi sweet lassi is a very delicious drink which can be prepared within few minutes in a simple style. Today I am sharing the recipe with you all. During summer time, yogurt based food keeps the body cool and I make lassi to refresh from scorching heat. Yogurt is very handy and it can be used in many ways. We all love yogurt based dishes such as raitas, buttermilk, curd rice, lassi or plain yogurt.
