Question: how many lemons make 2 tablespoons of juice?
Answer: One regular-sized lemon contains about 2-3 tablespoons of juice. Since all lemons aren't exactly the same, we like to stay on the side of caution and assume that one lemon contains 2 tablespoons juice. This means, if a recipe calls for 1 tablespoon of lemon juice, you'll need to use about ½ a lemon.
