If you do not have a tablespoon measure, you can use teaspoons instead. Here is how:
- Fill your teaspoon completely and level it off with a straight edge
- Count 3 level teaspoons — this equals exactly 1 tablespoon
- Add them together into your mixing bowl or measuring cup
This method works perfectly for any ingredient — flour, sugar, salt, baking powder, spices, oil, or liquid ingredients.
