Can I Buy Lemon Zest?

You can buy lemon zest in the spice section of your store but it is much cheaper to zest your lemon yourself. I purchased a zester and I have used it multiple times and it has already paid for itself. You can see the one I purchased here. What I love about the one I purchased is it has a plastic shield on the bottom that the zest falls into. Which makes containing it must less messy.

Do I Need to Use a Fresh Lemon?

You do not have to if you only have lemon juice and lemon zest already on hand. If you don’t, again a fresh lemon is much cheaper, especially if you already own a zester. Plus your lemon will have a fresher taste in your cookies.
