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. Preheat the oven to 400°F (200°C).

  2. Mix the baking powder (or baking soda and cream of tartar) with the salt and flour, then sift again.

  3. Rub the lard into the flour mixture until well combined.

  4. Grease the baking pans and prepare everything before adding the milk.

Make and bake

  1. Add the milk and knead the dough quickly.

  2. Roll out the dough to 1 inch thick and cut into small rounds.

  3. Bake for about 20 minutes, handling the dough as little and lightly as possible.

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 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 that holds the biscuits together as they rise.
Lard
Coats flour particles to tenderize the crumb and keep biscuits flaky.
Milk
Hydrates the flour so gluten and starch form the dough, adding moisture.
Baking powder
Releases carbon dioxide gas when moistened and heated, making the biscuits rise.
Baking soda
Reacts with cream of tartar to produce gas for rising and lift.
Cream of tartar
Acid that reacts with baking soda, releasing gas for rising.

The step that matters

Handle the dough lightly. Kneading or overworking develops gluten, making the biscuits tough and dense. Quick, gentle handling after adding milk keeps the texture tender and light.
