After juicing, measure into 1 tsp. amounts so that you have an equal portion in each ice cube tray...
Update: It's actually 1 tablespoon!
pour into tray and freeze! Easy!
The next day, just pop the lemon cubes out of the ice cube trays and place them into a zip lock bag. Now you'll have a measured amount of lemon juice whenever you need it. These can easily be cut in half for smaller amounts as well.
This took me all of 10-15 minutes (with interruptions from dear children)!
I love to add some lemon to my chicken noodle soup! And tuna isn't so fishy when you add just a bit of lemon juice. Another favorite use of mine is lemon juice with a bit of butter on fresh steamed veggies. It's nice to have these ready!
