Always end up with an aging half lemon in your fridge? If so chop them up and freeze them and you'll never want for ice and a slice in your gin and tonics!
Step 1: Take Your Old Lemon or Lime and Slice the Dried Out
If you end up with an aging half of a lemon or lime in your fridge, I find the best thing to do to make use of them is to slice off the dried out end, then quarter or slice them up. Once in pieces just put them into a freezer bag or tupperware and pop into the freezer.
Then whenever you need ice and a slice in a drink just throw a couple of these in!
