Place frozen cherries in the bowl of a food processor, along with sugar and process until smooth, scraping down the sides as you go.
Once smooth, add lemon juice to taste.
Freeze for 6-7 hours, or until firm.
Notes
Don't add all of the lemon juice in at once - you need to add it to taste. It also may seem like a strange ingredient, but it really brings out the flavour of the cherries. Think about it like salt in a savoury dish!
I have used frozen cherries in this recipe instead of fresh because where I live in the world (Australia) tomorrow is the first day of winter! So....no fresh cherries!
But, what can I say - I loooove me some sorbet! So frozen cherries it is!
That being said, I can't see why this recipe wouldn't work with fresh cherries - but full disclosure I haven't tried it with fresh cherries.
