A lovely recipe... the crumb topping is particularly nice. I added sugar to the fruit, but really don't think you need to. Good advice about the flour coating; the frozen blueberries can get a little runny when thawed/cooked. Would love to try it with fresh, just to see the difference. Goes really well with fresh homemade whipped cream. Thanks for posting ~ my hubby and I really enjoyed this! :)
This was a fabulous recipe. The proportions were perfect, though i added some cinnamon to the berries and the apples. My guests loved it and I will make it again.
