Full question: Many recipes mention "ratios" eg in the waffle recipe it is 2.5/1 and in the muffin it is 2/1. What is the meaning of these ratios and how are they used practically?
Response: The ratio is the comparison of fat to non-fat grams. Non-fat is the sum of carbohydrate plus protein. The recipes with those ratios are intended for the Classic Ketogenic diet which needs to be medically supervised. We are providing household measure for some of the recipes that are more liberal in carbohydrate. As a rule-of-thumb, 5gm is equal to 1 teaspoon but this is not always true for liquids and powders.
