Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Sift the baking powder, cream of tartar, soda, and salt into the flour.

  2. Rub the lard into the flour mixture.

  3. Preheat the oven to 400°F (200°C).

  4. Grease the pans and prepare a cutter and rolling pin.

Shape and bake

  1. Add the milk and knead quickly.

  2. Roll out the dough to 1 inch thick.

  3. Cut with a small round cutter and place in the greased pans.

  4. Bake for 20 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: acetaldehyde (pungent, ethereal).

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the structure of the biscuit as the dough sets in the oven.
Baking powder
Releases gas in the dough so the biscuits rise and become light.
Cream of tartar
Reacts with the soda to produce gas, adding lift and a tangy note.
Soda
Reacts with the acid cream of tartar to produce gas for rising.
Lard
Coats flour particles to shorten gluten, giving a tender, flaky crumb.
Milk
Hydrates the flour to form the dough and adds moisture and browning.

The step that matters

Add the milk and knead quickly. Overworking the dough develops gluten and makes biscuits tough. A quick, light handling keeps them tender, and the leavening gas is released best when the dough is not overmixed.
