In a very clean quart jar, tuck in sliced lemon rounds. Fill the jar about ⅔ of the way.
If you want any of the optional additions, tuck them in as you add lemons.
Cover with honey; it will take a couple pours and letting it settle until full.
Wipe jar rim and put lid on well.
Each day, flip/turn the jar and give it a burp. After two weeks you can taste and see where you are at, or sooner if it stops letting off gas.
Notes
Taste after 2 weeks and if you like it, move to fridge. If you want to see what it will taste like if you leave longer, leave longer! It lasts months in the fridge. If it doesn't get used up in cold and flu season, make lemonade with it!
