How many grams is half a tablespoon of cream of tartar?
½ tablespoon of cream of tartar ≈ 4.5 g
One teaspoon of cream of tartar weighs about 3 grams and one tablespoon is about 9 grams, so half a tablespoon comes out to roughly 4.5 grams. Cream of tartar is used by the teaspoon — about 3 grams each.
Small spoon amounts are where weighing has the biggest payoff: tiny errors compound in baking. If your scale reads in 1-gram steps you can measure cream of tartar directly. (For reference, one US cup is 144 g.)
