Lemon extract (pure lemon extract) is an aromatic cooking extract made from the essential oil from fresh lemons. Lemon extract can be used in breads, cakes, sauces, sorbets, custards or any recipe where a lemon flavor is desired.
When you see the word "pure" before the extract name it refers to a product that uses the natural ingredients along with alcohol to produce the extract, as opposed to an artificial flavoring.
This potent flavoring is typically used in small amounts. You can use this extract in everything from popsicles, cookies, cakes and even beverages.
This is a standard grocery store item. If you can't find it locally, you can also purchase extract in larger amounts, like 8 ounces vs small 3 oz bottles at Amazon.com.
