Chaas is a yummy drink from India that's made by mixing yogurt, water, salt, and spices together. It's kind of like a watered-down yogurt smoothie that tastes tangy and refreshing. Some people also like to add things like mint, ginger, or cumin to give it extra flavor. It's a great drink to have on a hot day because it's so cool and refreshing. Plus, it's good for your tummy because the yogurt has lots of healthy bacteria in it that can help your digestion. Yum!
