Lemons: just a splash of lemon juice
There are things that nature does not manufacture in a way that is appropriate to their needs. Lemons are also included. What do you do when you juice right z. B. only needs a cup of tea?
Often you really only need a splash or a little bit of lemon juice, so it's not worth "sacrificing" a whole lemon.
Then I roll a Zitrönchen on the countertop a few times back and forth - well, not until it gets dizzy - but, so that the juice inside of the cells is released.
Drill a short piece of straw into the side through the shell. Already you can remove the lemon juice splash. In a drinking cup with a lid or a plastic bag with zip-lock closure you have fun on such a Zitrönchen. Sour makes fun.
