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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

  2. In a bowl, mix flour, baking powder, salt, and sugar.

Make the dough

  1. Add milk and melted butter; stir until just combined.

  2. Turn the dough onto a floured surface and knead gently.

  3. Roll out to ½ inch thick and cut into rounds.

Bake

  1. Place on a baking sheet and bake for 12-15 minutes until golden.

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 pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

All-purpose flour
Provides the main structure as gluten forms when the dough is mixed and kneaded.
Baking powder
Releases gas in the oven, lifting the biscuits so they rise and become light.
Milk
Hydrates the flour and brings the dough together, adding moisture to the crumb.
Melted butter
Adds fat that coats flour strands, tenderizing the crumb and adding richness.
Sugar
Adds a little sweetness and helps the surface brown in the oven.

The step that matters

Stir only until just combined, and knead gently. Once liquid meets flour, gluten starts to develop. Overmixing or heavy kneading toughens the dough and makes the biscuits dense rather than tender.
