Don't know if this will be read, but do you recommend certain varietals of apple over others when baking sweets? I have heard green apples like Granny Smith pair well because the sugars that are added and already present come out after heating.
After you added the apples to the caramel, you didnt mention that you then baked them in the oven, you then took them out and put the pastry on and baked again. No mention of how long or at what temperature you baked them. Please explain your method more clearly next time.
First time making one I got the sugar to boil a small bit, (not nearly as much as yours) and it tasted like ass. bit of a burnt aftertaste, so the next time I tried I got it to a light brown color and it tasted much better, probably just me idk.
