Wash,remove pips and stems from fruit, all fruits with skin need to be blanched to remove skins easy,fo this as each fruit comes int season
Cut large fruit into cubes or slices and grapes into halves.each time weigh your fruit write down weight.Use half amount of this weight in sugar and sprinkle evenly over fruit. Pour a good quality high proof dark rum over fruit unti it is about1/2 inch or just over 1cm over the fruit.Fruit might have to be weight down with small plate.
Tie a linen cloth over opening and store in fridge,cold dark room or cellar.Keep adding fruit, sugar and rum throughout summer.Gently swivel the pot before adding new fruit.after you have added your last chosen fruit,leave to stand for 4-6 week.add more rum as it evaporates.
I add a cinamon stick to mine and use a earthwear pot.
