FAQ

Does sifting Whey protein powder change the cup weight?
Yes — sifted Whey protein powder is lighter per cup because of the added air. Our table uses unsifted values; reduce by about 15–20 % if your recipe calls for sifted.
Should I pack Whey protein powder into the measuring cup?
Only if the recipe says 'packed'. By default, spoon Whey protein powder into the cup and level off with the back of a knife for the most consistent weight.
