Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Vinegar Cookies

Oven, in the book's wordsA quick oven

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.

Prepare the dough

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

  2. In a large bowl, mix molasses, butter or lard, eggs, vinegar, ginger, and baking soda.

  3. Gradually add flour until the dough is firm enough to roll.

Shape and bake

  1. Roll dough to about ½ inch thick and cut into round cakes.

  2. Place cookies on a baking sheet and bake until golden.

Butter and flour 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

Molasses
Adds sweetness, moisture and a dark, rich flavour to the dough.
Butter or lard
Adds fat for tenderness and a richer texture in the cookies.
Eggs
Bind the dough and add structure as it bakes.
Vinegar
Acidity reacts with the baking soda to lift the cookies and add tang.
Baking soda
Reacts with the acid in vinegar and molasses to produce gas that makes the cookies rise.
Ginger
Contributes warm, spicy aroma to the cookies.

The step that matters

Adding the flour. Flour should be added gradually so the dough becomes firm enough to roll without becoming tough. Too much flour at once can make the cookies dry and dense, and the dough needs enough gluten development to hold its shape.

Swap the ginger

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Capersfits better
  4. Gingerthe original

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