Grafton Milk Biscuits

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 the sponge

  1. Boil and mash the potatoes.

  2. Add brown sugar and pour boiling water over the mixture to soften.

  3. When tepid, add the yeast and let it rise until light.

  4. Warm the butter in the milk, then add salt, baking soda, and enough flour to make a stiff sponge.

  5. When risen, work the dough on a floured surface, then place it back to rise again.

Shape and bake

  1. Once risen, roll into cakes and let them stand for 30 minutes.

  2. Bake in a 400°F (200°C) oven until golden.

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

What each ingredient does

White potatoes
Starch from the mashed potatoes adds moisture and a soft, tender crumb.
Yeast
Yeast ferments the sugars and produces gas that makes the dough rise.
Milk
Milk adds richness, softness, and browning from its milk sugars and proteins.
Butter
Butter adds fat, which tenderizes the crumb and gives a rich flavor.
Flour
Flour provides the structure that holds the risen dough together.

The step that matters

Letting the sponge rise until light. Yeast needs time and warmth to build gas and structure; under-proofed dough bakes dense, while over-proofed dough can collapse and lose its rise.

Swap the potato

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

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

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