Can I drink butter milk without having problems?
I have left over butter milk from cooking and hate to waste it.
Assuming it is well within expiration date and that you are not allergic to milk products, then yes, drinking butter milk should definitely be safe. It is actually a common practice in India to drink butter milk at the end of a meal.
Certainly! It is great on hot days and hence very popular in southern India. Buttermilk is just like drinkable yogurt and you get your yogurt fix for the day and quench your thirst too! Go for it.
