Why it works: Clove and mace are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 8,400 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓

Mushroom Powder

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Clean and chop the mushrooms and onions.

  2. Add cloves, mace, and white pepper.

  3. Heat gently until the liquid from the mushrooms evaporates.

Dry

  1. Spread the mixture on baking sheets.

  2. Dry in a slow oven at 300°F (150°C) until completely dry.

Grind

  1. Grind into a powder.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms
Form the bulk of the powder and release liquid that must evaporate before drying.
Onions
Add savory sweetness and aroma as they dry alongside the mushrooms.
Mace
Adds a warm, nutmeg-like aroma to the powder.
White pepper
Adds mild, sharp pungency and aroma.
Cloves
Add a strong, warm aroma, so a small amount goes a long way.

The step that matters

Dry until completely dry. Any leftover moisture in the mushroom and onion mixture can cause clumping, uneven grinding, and spoilage. Heating gently first drives off the free liquid, and a slow oven then removes the remaining water evenly, so the pieces become brittle enough to grind into a powder.

Swap the white pepper

How well each one fits the dish's main ingredients (mushroom, onion, clove, mace):

  1. Thymefits better
  2. Allspicefits better
  3. Nutmegfits better
  4. White pepperthe original

Fit is the average pairing score against mushroom, onion, clove, mace. Candidates are from the same food group and used in at least 100 recipes.
