Question: how much garlic powder equals 1 tablespoon garlic salt?
Answer: Just be careful to use the proper ratio of garlic to salt (generally 3-to-1 salt to garlic powder). Garlic salt is 3 parts salt and 1 part garlic, plus an anti-caking agent. That means that 1 tsp of garlic salt contains 1/4 tsp of garlic powder, or a 4 to 1 substitution ratio.
