A teaspoon is a small spoon used for stirring tea or coffee, eating desserts, and measuring ingredients when cooking. It's one of the smaller spoons you'll typically find in a silverware drawer, about the size of your thumb from tip to base.

When a recipe calls for a teaspoon of vanilla extract or two teaspoons of sugar, it means a specific amount: one teaspoon is about 5 milliliters. Cooks use special measuring spoons to get this amount precisely right, because even small differences matter in baking. If you add three teaspoons of baking powder instead of one, your cake might rise too much and taste bitter.

Today, teaspoons are essential in kitchens worldwide, perfect for adding just the right amount of cinnamon to oatmeal or tasting soup to check if it needs more salt.

You might also hear someone say they'll do something with a teaspoon, meaning they'll do it carefully and in small amounts, like digging a hole with a teaspoon instead of a shovel, which would take a very long time but shows dedication.
