What is the difference between lemon zest and lemon extract in terms of flavor intensity and usage in recipes?

Lemon zest is the outer peel of a lemon that contains natural oils and provides a strong, fresh citrus flavor. It is used to add a bright, tangy taste to dishes. Lemon extract is a concentrated liquid made from lemon oil and alcohol, providing a more intense lemon flavor. It is often used in baking to enhance the lemon taste in recipes.
