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.

Make the batter

Dissolve the yeast in 3 tablespoons of water.
Mix the flour, dissolved yeast, water, and salt together, beating thoroughly.

Rest and fill

In the morning, add the melted butter and half‑fill muffin pans.
Let the mixture rise to the top for about 30 minutes.

Bake

Bake in a 400°F (200°C) oven for 30 minutes.

What each ingredient does

Flour: Provides the structure that holds the batter's gas bubbles and sets the crumb.
Yeast: Ferments the batter, producing gas that raises it and creates the crumpet's holes.
Butter: Adds fat, which softens the crumb and gives a richer flavour.
