Question: how much garlic powder equals garlic salt?
Answer: 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. My family watches our salt intake so we usually use garlic powder in place of garlic salt and just add a tiny bit of salt to recipes.
