Save me a glass :)
I'm not sure if everyone knows this or not. My mum's made it ever since I can remember but anyone I've mentioned it to has asked me what it is so I thought I'd share it with the world.
Pour guava juice and lemonade into a jug or bottle at a ratio of 1:1 or 2:1, depending on your taste preference.
1:1 will be thinner and sweeter
2:1 will be thicker and have more of the guava taste coming through.
I prefer 2:1.
This is optional, it's to decorate your glass (like I did in the picture).
Cut the lemon in half. Rub the rim of the glass onto it. Dip the glass into the caster sugar.
Put the glass into the fridge or freezer until you're going to use it to drink.
