Potato Biscuit

Ingredients

Directions

Prepare the potatoes

  1. Wash, peel, and boil the potatoes in enough water to cover them.

  2. Mash the potatoes finely, then mix in the salt and sugar.

  3. Drain the potatoes well before mashing.

Make the dough

  1. Rub in the butter, then add part of the flour and part of the warm milk.

  2. Stir in the yeast, then add the remaining milk and flour.

  3. Knead the dough for 12-15 minutes, then cover and let it rise overnight.

Shape and rise

  1. In the morning, roll out the dough and cut it with a biscuit cutter.

  2. Let the biscuits rise for 1.5 to 2 hours before baking.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
Add moisture and a soft, tender crumb to the dough.
Yeast
Ferments the dough, producing gas that makes it rise.
Flour
Provides structure once kneaded, holding the dough together.
Butter
Adds fat that tenderizes the crumb and enriches flavor.
Milk
Hydrates the flour and helps form a smooth, elastic dough.
Sugar
Feeds the yeast and adds a little sweetness and browning.

The step that matters

Drain the potatoes well before mashing. Excess water from boiled potatoes dilutes the dough and changes its hydration, so the dough can end up too wet and sticky. Draining removes that surface water, keeping the measured milk and flour in balance.

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.
