Put cranberries in a clean 1 litre jar (they filled it halfway)
Add enough sugar to fill in the gaps and cover by about 1 cm.
Pour in about 1 litre of gin and seal the jar.
Give it a good shake.
The above photo is the next day when the colour starts to leave the fruit and the sugar starts to dissolve
Day 2 shows there is still some sugar at the bottom of the jar but the colour is a lovely red now. Give it a shake.
By day 3 the sugar is dissolved
Put the jar in a cupboard for a few weeks to let the cranberry flavour and colour develop. It can be left for a while if you forget. Then all you have to do is strain the mixture through some muslin into a clean bottle and enjoy!
