You will be soaking with the peel intact, so wash the lemons well. Of course, you don't want it moist! Pat dry well to prevent molding.
Leave one lemon intact, then slice the rest into thin slices.
Pack a jar in this order: lemon slices, granulated sugar, honey, lemon slices...
Take the whole lemon, cut it in half, and squeeze out the juice. Pour this juice onto the very top layer of the jar, leaving no gaps.
Let it sit for about a week, then it will be ready to drink. The lemon slices will stick to each other, so give it a stir every once in a while with a clean spoon.
Once it's finished, store in the refrigerator. My preferred way to drink this is in a 1 to 1 ratio with soda and water. Crisp and delicious.
This jar has pink grapefruit inside it. They should be soft enough to eat as well, so add them to your drink and enjoy a little nibble.
To aid in preventing heat exhaustion, add some salt. Use a pinch for 200 ml worth of lemonade. You can't taste the salt at all.
