A great way to use up large amounts of watermelon. Mostly when you buy one, they are huge and that means you eat 2/3 of it and the rest will sit around. Don´t let it sit in the fridge, make a great tasting ice cream. Refreshing and a good use for the leftovers.
600 ml watermelon puree
250 ml buttermilk
50 g sugar
1 1/2 tsp lemon juice
just use a blender, blend first the watermelon pieces, add sugar and buttermilk and lemon juice.
USE a fine sieve! It does not make sense to make a wonderful ice cream when it gets gritty. Sieve the liquid and get the rest of the pips and chunks out and freeze it.
