Question

If you use 15 oz of milk, how much flour
should you use?

Answer 1

The amount of flour needed will depend on the recipe and the desired consistency. However, a common ratio for making a basic roux (a mixture of flour and fat used for thickening sauces) is equal parts flour and fat by weight. So, if you are using 15 oz of milk, you could start with 15 oz of flour.
