Can you use fromage frais in cheese sauce?

Yes, you can use fromage frais in cheese sauce as a lighter alternative to cream or traditional cheese. It adds a creamy texture and a tangy flavor, though it may not provide the same richness as other cheeses. To ensure a smooth sauce, mix it in gradually and consider combining it with grated cheese for added flavor. Just be cautious with heat, as fromage frais can curdle if cooked too rapidly.
