Use a mix of apples if you can for different textures. I used McIntosh, Honeycrisp, and Granny Smith.
Fresh berries are amazing when they're in season, but frozen is great too. If you can't find marionberries try blackberries, boysenberries, or raspberries.
The roll of almond paste that I purchased was 7 oz, I used the whole thing and it turned out great!
