Thanks for the tips. The jar of cherries I used came with a lot of juice and it was really sweet. That’s why I added the lemon. I guess it depends on the types of cherries you’re using. I find the fruit jars in North American very sweet, some even have syrup in them. Using flour to thicken is always good too as it’s more of the traditional method.

In this instance, I would even suggest omitting the sugar since the jar of cherries is already sweetened.
