What you’ll learn

  1. The bag of Granny SmithsPick Granny Smiths for a first standing pie, name why Golden Delicious is a different pie, and scale Stella's ten-to-twelve-slice filling.Buy Granny Smiths. They hold. Golden Delicious taste louder and bake softer. Red Delicious is sauce. An adult peels. You measure.
  2. Pectin is the mortarExplain apple cells, pectin, and the 183°F collapse, and say why acid, density, and a 195°F finish keep slices standing.Cells are water balloons. Pectin is mortar. Acid and density keep it. A boil is sauce. Do not mix a keeper with a saucer.
  3. Smash the butterSmash a 1:1 butter-to-flour dough, fold it for flakes, and chill it so the bottom crust stays crisp.Gluten is strength. Butter is tenderness and a waterproof bottom. Smash, fold, chill two hours. Sticky dough is already too warm.
  4. Macerate, then starchCut even half-inch wedges, macerate three hours, then add tapioca and mound the fruit in a glass plate.Sugar shrinks the fruit. Tapioca waits. Cinnamon is a hint. Nestle the slices. Chill the assembled pie 30 minutes.
  5. Bake to 195, then waitEgg-wash and vent the pie, bake to 195°F, cool completely, and store a sugared fruit pie safely.Wide vents. Glass plate. 400°F to 195°F. Cool before you cut. Two days on the counter, then the fridge. Glue is a boil. Soup is a hot knife.

Questions this course answers

Why does Stella pick Granny Smiths for a first apple pie?

Stella: Granny Smiths are high in pectin, hold their shape, and keep the filling thick. Their tartness offsets ice cream. Kenji scored them a 5 for flavor but agreed they hold almost forever.

In your own words, why does a more acidic apple hold its shape better in a pie?

Kenji explains that pectin is stronger at lower pH, one reason Granny Smith tends to hold better than Red Delicious in his tests. Lemon juice is the same kind of lever in many recipes.

Match each move to the job it does in Stella's first pie

Smash is flake and a dry bottom. Macerate is shrink. Tapioca is late insurance. 195 is tender, not sauce.

Put Stella's first apple pie in the order that keeps slices standing

Dough first so it can chill while the fruit shrinks. Starch last. Oven after another chill. Knife last of all.

Stella bakes the pie to 195°F in the center, cooler than a boil. Why?

Stella: bringing the filling to a boil makes apples release their juices completely. 195°F keeps them plump and juicy with enough structure to hold their water.

Iowa State Extension, citing USDA, says a fruit pie made with sugar may sit at room temperature for how many days?

USDA via Iowa State Extension: fruit pies made with sugar are food-safe at room temperature up to two days. Then refrigerate about two more days, or freeze up to four months. Pumpkin and cream pies follow the two-hour clock instead.
