Another tip that my mother, the Original Diva, taught me was to always pity the lemon about to be squeezed for Tabbouleh, Lemon Bars, or Lemon-Lentil Soup and then unceremoniously discarded. She suggests I take a few moments to quickly rasp the lemon(s) I will be using on a MicroPlane and stash the bounty in a Ziploc in the freezer. And so that's what I do.
The four lemons above were about to be squeezed for Tabbouleh. How could I let them go to waste??Of course if you do it every time, you risk a glut of lemons. So only replenish your supply as your stash gets low. There is nothing better than reading a recipe that requires lemon zest and knowing all you have to do is reach into your freezer and snap a bit off the frozen pile.
