Instead of going for the regular mayonnaise bought off the shelves I thought why not try to make some homemade and a fat free mayonnaise. Well although my idea was great I struggled with the execution. But no more attempting blindly, can you share with me your tested mayonnaise recipe? Well instead can you share the better option than that, can you tell me how do I make a fat-free mayonnaise substitute? The ingredients and accessories I am aware of that I might need are non-fat butter substitute, a shallow saucepan, a mixing bowl, non-fat sour cream and the whisk. What else will I need? Help please.
