French Rolls

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the sponge

  1. Peel and boil the potatoes in 2 quarts of water until tender.

  2. Press and drain the potatoes through a colander and let cool.

  3. Add flour to the potatoes to make a thick batter and beat well.

  4. When lukewarm, add ½ cup potato yeast to the batter.

  5. Make this sponge early in the morning and let it rise until light.

Make the dough

  1. Transfer to a bread pan and mix in 1 teaspoon salt and ½ cup lard.

  2. Add enough flour to form a soft dough and mix well.

  3. Set the dough in a warm place to rise, kneading down and letting it rise again 5 or 6 times.

Shape and bake

  1. Cut the dough into small pieces and mold into rolls about 1 inch thick and 5 inches long.

  2. Roll the pieces in melted butter or sweet lard and place in well-greased baking pans.

  3. Press the rolls closely together, about ½ inch wide.

  4. Let rise for a short time and bake for 20 minutes at 400°F (200°C).

  5. If the tops brown too quickly, cover with paper.

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.

  1. Flour + buttertop 12% of all pairs

    Shared aroma: isobutyraldehyde (malty, green).

    Shared aroma: (z)-4-heptenal (biscuit, cream).

    Shared aroma: isobutyraldehyde (malty, green).

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

Potatoes
Add moisture and a soft, tender crumb to the rolls.
Flour
Forms the gluten structure that gives the dough its strength and rise.
Potato yeast
Ferments the sponge so the dough rises and becomes light.
Lard
Adds fat that tenderizes the crumb and softens the texture.

The step that matters

Letting the dough rise repeatedly. Each knead-and-rise cycle releases built-up gas and redistributes yeast, building gluten strength and a light, even crumb. Rising too little or too long can leave the rolls dense or collapsed.

Swap the potato

How well each one fits the dish's main ingredients (flour, butter):

  1. Shallotfits better
  2. Leekfits better
  3. Arrowrootfits better
  4. Potatothe original

Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
