Make-Ahead: Cheesecake (without curd) can be refrigerated up to 4 days. Freeze whole or slices (wrap in plastic then foil) for up to 2 months; thaw overnight in fridge. Swaps: Use GF graham crackers for gluten-free; swap lemon for lime or orange; blueberry swirl (add compote before baking). Mistakes to avoid: Cream cheese and eggs must be room temp. Do not overmix. Wrap pan with triple heavy-duty foil. Cool in oven fully to prevent cracks.
