Intro: This is an old country recipe from Suffolk, England. It was handed down from my neighbour's great aunt, who lived on the Suffolk/Norfolk border. It's not really a recipe, more just a loose set of instructions. The nice thing about sloe gin is that it lends itself to improvisation; because everyone in the countryside seems to know how to make it, everyone tends to make it a little differently. It's useful to have some basic guidelines to start with though, before one starts improvising.
This recipe is enough for two bottles of sloe gin
Gin: one litre
Sloes: (more on that in the next step)
Sugar: approximately 300 grams (more on that as well)
Container for collecting sloes (we used plastic bags and got juice all over us. I would recommend a plastic Tupperware or something similar)
Large needle or small fork or anything that you can pierce with
