To make sloe gin, start with 500 grams of frozen sloe berries.

Prick each fruit to puncture it, then put the fruit in a 1.5-liter jar that can be sealed tightly.

Add 250mg of caster sugar, and 750ml of your chosen brand of gin.

Then, seal the mixture and place the bottle in a cool, dark place.

In the first few days, shake the jar daily to help the sugar dissolve.

Wait at least three months - but no more than six - to open the bottles, strain out the spent fruit, and then rebottle.

Sloe gin can be sipped straight either warm or cold; both approaches are delicious!
