Chocolate Ice-Cream made with Lactose Free milk
According to the University of Virginia Health System, ice cream contains approximately 6 grams of lactose per 1/2-cup serving and Lactose Free milk has the same properties as cowis milk only difference is that it enhanced with the lactase enzyme.
So, You can make lactose free milk ice cream by using cow milk.However, it may not have the same texture or creaminess as ice cream made with cream. you can use coconut cream or pureed medium-firm or firm drained silken tofu to replace heavy cream, using a 1:1 ratio.
