Potato Biscuits

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. Mash the boiled potatoes and mix with boiled milk.

  2. Let it cool.

  3. Add the dissolved yeast, lard, and salt to the potato mixture and cover the mixture.

  4. Let it rise overnight.

  5. In the morning, work in enough flour to form a stiff dough.

  6. Set the dough in a warm place to rise again.

Bake

  1. Bake in a preheated oven at 350°F (175°C).

  2. Butter the tops while baking.

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: isobutyraldehyde (malty, green).

Milk and flour 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

Potatoes
Provide starch and body, giving the biscuits a soft, tender crumb.
Yeast
Ferments the dough so it rises and becomes light and airy.
Flour
Builds the stiff dough structure that holds the risen shape during baking.
Milk
Adds moisture and richness, softening the crumb and aiding browning.
Lard
Adds fat that tenderises the crumb and gives a rich texture.

The step that matters

Let the dough rise overnight and again in a warm place. Yeast needs time and warmth to produce gas that raises the dough. Under-proofed dough bakes dense, while the stiff dough must be rested enough to hold its rise in the oven.

Swap the potato

How well each one fits the dish's main ingredients (milk, flour):

  1. Arrowrootfits better
  2. Potatothe original
  3. Sweet potatofits about as well
  4. Parsnipfits about as well

Fit is the average pairing score against milk, flour. Candidates are from the same food group and used in at least 100 recipes.
