Not the most balanced shopping list I've ever written: 1 bottle Finlandia vodka 3 enormous grapefruits 1 air-tight container

Notably skipping the all-important meat, fish, dairy and vegetable components of an effective weekly shop, but fear not - there's a plan.

It's not even complicated. Strip the zests off the grapefruits, lob in the vodka, seal and in about two weeks, I'm going to add a couple of ounces of sugar syrup, et voilà I'll have a limoncello. Only grapefruitier. Grapefruitcello? Definitely not as catchy.
