Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Bran Gems

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°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 350°F (175°C).

Make the batter

  1. In a bowl, cream the shortening and sugar together.

  2. Add the sour milk and mix well.

  3. Stir in the cooking bran, flour, baking soda, and salt until combined.

  4. Fold in the raisins and nuts if using.

Bake

  1. Drop spoonfuls of the batter onto a greased baking sheet.

  2. Bake for 15-20 minutes or until golden brown.

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.

    Shared aroma: isobutyraldehyde (malty, green).

Milk and flour barely smell alike, yet cooks put them together in 78,219 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

Cooking bran
Adds fibrous bulk and a hearty texture to the batter.
Sour milk
Provides moisture and acidity that reacts with the baking soda to lift the batter.
Baking soda
Reacts with the acidic sour milk to produce gas, helping the gems rise.
Flour
Provides the structure that holds the batter together as it bakes.
Shortening
Adds fat that tenderizes the crumb and carries flavor.
Raisins
Add sweetness and chewy pockets of moisture throughout the gems.

The step that matters

Stir in the dry ingredients until combined. Overmixing once flour is added develops gluten, which can make the gems tough and dense rather than tender.

Swap the nuts

The recipe marks nuts as optional. How well each one fits the dish's main ingredients (raisin, sugar, milk, flour):

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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