Soda Biscuit

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the dough

  1. Mix the flour with baking soda and cream of tartar or baking powder, then add coarse sea salt to taste.

  2. Handle the dough as little as possible and shape it quickly.

Bake

  1. Place the biscuits in hot greased pans.

  2. Bake for 8 minutes 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: delta-dodecalactone (sweet, creamy).

    Shared aroma: isobutyraldehyde (malty, green).

    Shared aroma: acetaldehyde (pungent, ethereal).

Flour and butter 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

All-purpose flour
Forms the main structure of the biscuit dough.
Baking soda
Reacts with the acid in the dough to produce gas that lifts the biscuits.
Cream of tartar
Provides the acid that activates the baking soda for rising.
Baking powder
Supplies its own acid and base so the biscuits rise without a separate acid.

The step that matters

Handle the dough as little as possible and shape it quickly. Overworking develops gluten in the flour, making the biscuits tough and dense. Quick handling keeps the dough tender and lets the leavening gas lift it well in the hot oven.
