What you’ll learn

  1. Four bricks, not a tinPick four full-fat cream-cheese bricks and Susan Reid's sour-cream New York over a foil tin, a Basque cake, or a no-bake, and scale a 10-inch filling.Buy bricks, not a tub. Sour cream is the New York tell. Basque and no-bake are later. An adult owns the oven. You measure.
  2. Eggs are the wallsExplain cheesecake as a baked custard, name 140/150/175/185°F, and say why overbaking, overmixing, and a shock cool crack the top.Eggs are the walls. 175 at the edge is silk. 185 is a crack. Mix low. Coast in the oven. A water bath is later insurance.
  3. The cookie floorPress, dock, and prebake Susan's shortbread in a springform, and name graham crumbs as Stella's later 1928 floor.Shortbread tonight. Dock so it does not dome. 400 then 325. Graham is Stella's later cake. Three tablespoons of flour is insurance.
  4. Mix slow, pull at 175Warm the bricks, mix on low, add eggs one at a time, and pull the cake at 175°F while the middle still jiggles.Warm, scrape, one egg at a time, zest last. It will look underbaked. The probe does not crack it. Overbaking does.
  5. Coast, then waitCoast one hour in the dead oven, chill before cutting, store the custard on the two-hour clock, and tell Basque heat from New York heat.Door propped one hour. Fridge before the knife. Two hours on the table, three to four days cold. Cherries hide a crack. 500°F is a different cake.

Questions this course answers

Susan Reid turns the oven off when the cheesecake hits 175°F an inch from the edge. Why?

Susan: the middle will look underbaked. Heat keeps travelling inward. Cooking it more overcooks the eggs and cracks the top. Her 195°F test cake was grainy and dry.

In your own words, why does overbaking a cheesecake make it crack and turn grainy?

Susan Reid: whites begin to set around 140°F, yolks around 150°F. The more you cook past that, the tighter the proteins become. PJ Hamel: 185°F anywhere almost certainly cracks the top.

Match each move to the job it does in Susan's first cheesecake

Warm bricks are smoothness. Low speed is a whole top. 175 is silk. The hour is still the bake.

Put Susan's first New York cheesecake in the order that keeps the top whole

Crust first so it can cool. Filling next, slow. Oven after the probe says 175. Knife last of all.

PJ Hamel tested four ways to stop a cheesecake cracking. Which scored highest?

PJ scored a water bath 9.5/10. Steam was 5.5, strips 7, a plain oven 5. Tonight Susan's first cake still uses the thermometer and the coast instead of requiring a bath.

USDA FSIS leftover guidance: after it is cold, homemade cheesecake keeps in the refrigerator about how many days?

USDA FSIS: leftovers 3 to 4 days in the fridge, or freeze 3 to 4 months. The two-hour clock starts when the cake leaves the fridge. Illinois Extension puts egg-and-dairy pies on that same two-hour clock, never on the counter overnight.
