This recipe is almost embarrassingly easy. So embarrassing that when people demanded the recipe, I felt foolish when I couldn't reciting it from memory. Honestly, it's that easy.
The only problem is that Bittman only accounts for one pan to be made at a time.
Fool, clearly we will want at least 4 pans of this stuff.
1 cup flour
1 tsp salt
1/2 cup grated Parmesan
4 tbsp cold butter
1/4 cup cream
2 tbsp chopped sage (fresh if possible)
Pulse flour, salt, Parmesan and cold butter in a food processor (even this is optional, I just combined it in a large bowl).
Add cream and chopped sage.
When just combined, roll as thinly as possible, score into squares, sprinkle with salt and bake at 400 degrees until golden.
Let cool, then break into pieces.
