Lemon zest

Baked goods may easily be improved by adding a tiny pinch of lemon zest. The small shavings of citrus fruit's vividly colored and strongly flavored outer skin are known as zest, often known as the lemon peel.

You may use the lemon zest as a concentrated source of acidity and flavor if you have frozen or dried lemon zest on hand. It functions well in recipes and desserts where lemon is the main flavor. 1/2 teaspoon of lemon extract or two tablespoons of lemon juice is equal to one teaspoon of lemon zest. It will give you the closest flavor match possible. For the recipe to work properly, you might need to add more liquid, especially if you're baking.
