I thought I had referenced this before in this blog, but I’m not seeing a post so here we go again.
We were going to need lemon juice for our peach recipes, so after draining out the juice, I cut the lemon rinds up, and stuck them into an empty ice cube tray. In the original recipe, you use lemons with the liquid and pulp intact but I find this is a good way to use up the lemon rinds from other projects. Pour in enough white vinegar to cover and freeze.
After they freeze, you can throw a few into the garbage disposal, sprinkle with baking soda, turn on the hot water and then start the disposal. Leaves a lovely lemon smell throughout the kitchen!
