I don't know about you, but for me lemon is THE citrus. It smells great, can be used for desserts or to brighten pasta dishes, for cleaning and deoderizing ... but you knew that already! But what do you do when you have way more lemons from your tree than you can reasonably use?
You make sliced lemon ice cubes!
Step 1: What you need:
A muffin tin or a mini loaf tin
Large zipper type bag
Knife and cutting board
I have not tried it with limes, but I see no reason why you could not make that substitution.
