Lemons are an essential tool is any kitchen. Both the juice and zested peel is used as flavoring. They are used in desserts, marinades, drinks and sauces.
Allowing Lemons to come to room temperature before squeezing (or heating briefly in a microwave) makes the juice easier to extract. When Lemon juice is sprinkled on certain foods that tend to oxidize and turn brown after being sliced, such as apples, bananas and avocados, the acid acts as a short-term preservative by denaturing the enzymes that cause browning and degradation.
