Soda Biscuit

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. Dissolve the baking soda in the sour milk.

  2. In a bowl, mix the flour, lard, and salt.

  3. Add the sour milk mixture to the dry ingredients and stir until combined.

  4. Let the dough rise for 15 to 20 minutes.

Bake

  1. Preheat the oven to 350°F (175°C).

  2. Bake the biscuits until golden brown.

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).

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
Provides the structure that holds the biscuits together as they bake.
Lard
Adds fat that shortens gluten strands, giving a tender, flaky texture.
Baking soda
Reacts with the sour milk's acid to release gas, helping the biscuits rise.
Sour milk
Supplies acidity that activates the baking soda and adds moisture to the dough.

The step that matters

Stir only until combined. Overmixing once the milk meets the flour develops excess gluten, which makes biscuits tough. A soft, barely mixed dough keeps them tender and light.
