Flour and Potato Rolls

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 the dough

Boil and dry the potatoes.
Mix the potatoes with sweet cream and milk.
Rub the mixture through a wire sieve into the flour.
Mix the warm milk with a little yeast and add it to the flour mixture.
Knead into a dough and let it rise in a warm place.

Shape and bake

Form the dough into rolls and bake at 400°F (200°C) 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.

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.
Flour: Provides the structure that the dough builds around as it is kneaded.
Yeast: Produces gas as it ferments, making the dough rise and become light.
Sweet cream: Adds fat and richness, softening the crumb and promoting browning.
