Step 1

Place the cranberries, gin, 100g of the sugar and the vanilla pod into a large, sterilised jar, and give it a good stir.

Step 2

Cover and place in a dark place for a minimum of 1 month. I place mine in a kitchen cupboard. Stir it every other day, or as often as you remember to! About every 2-3 days, I squash some of the cranberries with the back of a spoon, when I'm stirring the mix. You can leave them whole, if you like, especially if you are planning to use the cranberries after.

Step 3

At the end of 3 weeks, taste it, and add more sugar if you think it needs it. Steep it for another week, at least. If you have the patience, go for another month for a deeper flavour.

Step 4

To drink, strain through a sieve or, if you like a crystal clear gin, strain though a double layer of muslin or cheese cloth into a sterilised bottle. Store in a dark cupboard as you would your other drinks.
