If you are looking for non-dairy alternatives, know there are plenty of options you can buy in the grocery store or make at home. For example, instead of cream, use dairy replacements like coconut cream; instead of milk, use oat milk or homemade cashew milk; Instead of butter, use olive oil or bananas for sweet recipes; and instead of sour cream, use plant-based soft cream cheese, usually made from coconut or soy milk.
