Tablespoon

The tablespoon is a ubiquitous unit of volume measurement used extensively in both cooking and baking recipes. In the United States customary system, one tablespoon is equivalent to exactly 3 teaspoons, 1/2 fluid ounce, or approximately 14.79 milliliters. When developing recipes, this is usually rounded to 15 milliliters for simplicity and alignment with international metric standards. However, regional variations exist that can catch bakers off guard. In Australia, a standard tablespoon is defined as 20 milliliters and contains 4 teaspoons instead of 3, creating a significant difference in volume that can alter the balance of leaveners or seasonings in a recipe.

Using tablespoons requires level measurements for accuracy, especially when dealing with active ingredients like baking powder, baking soda, yeast, or potent spices. Scooping a heaping tablespoon of baking soda instead of a leveled one can introduce double the intended amount, leading to a bitter, metallic taste and an collapsed structure in your cakes. For dry ingredients, the ingredient should be spooned into the tablespoon and swept level with a flat edge, while liquids should be poured right to the brim of the measuring spoon without spilling over.
