Just an apple and a lemon. A light and delicious drink. I am amazed at how delicious it is.

Remove the pot from the heat and let the mixture cool.
Pour the tonic drink through a fine sieve to remove the lemon and apple pieces.
Either serve the tonic warm or let it cool and optionally serve with ice cubes.
Enjoy the refreshing lemon-apple tonic and enjoy it!
Note: This tonic drink is light and delicious. You can drink it warm or chilled, depending on your personal taste. If you want it sweeter, you can add some honey or sugar. Feel free to experiment with different variations, for example by adding mint leaves or ginger to give the drink an additional flavor.
