Should I freeze finished products made with phyllo before or after I bake them?
Whenever I make spanakopita ahead of time, I freeze them before baking. I think you end up with a crisper, fresher final result.
Definitely not after - you'll lose all texture that you work for in using phyllo to begin with.
You can freeze after, though. Then just re-crisp in an oven or toaster oven.
