Tip 2

Place the pie on a baking sheet to catch any potential overflow from the custard during baking.

Tip 3

Cover crust edges with foil strips during the final baking stage to prevent over-browning while the streusel finishes cooking.

FAQ

Can I make this pie dairy if I'm not keeping it parve?

Yes, substitute regular butter for margarine and regular sour cream for parve sour cream using the same quantities for a traditional dairy version.

What if I don't have pumpkin pie spice?

Mix together cinnamon, nutmeg, ginger, and a pinch of cloves. Use about 2 teaspoons cinnamon as the base and add small amounts of the other spices to taste.

How long will this pie keep?

Store covered in the refrigerator for up to 3 days. The custard layer is best within 24 hours, though the pie remains safe to eat longer when properly stored.
