Why it works: Mace and white pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,695 recipes. Both carry myrcene, which smells balsamic, herbaceous. The science ↓
Mushroom Powder
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the mushrooms thoroughly and scrape out the black parts. Discard any worm-eaten mushrooms.
Place the mushrooms in a saucepan over medium heat without adding water. Add the onions, mace, and white pepper.
Simmer and shake the mixture until all the liquid has evaporated.
Dry and store
Spread the mixture on baking sheets and dry in a slow oven at 300°F (150°C) until completely dry.
Once dry, grind the mixture into a fine powder and store it in small, tightly corked bottles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body of the powder, releasing moisture that must fully evaporate during cooking.
- Onions
- Add savory sweetness and aroma as they cook down with the mushrooms.
- Mace
- Contributes warm, aromatic spice flavor to the powder.
The step that matters
Drying until completely dry. Any moisture left in the mixture can prevent the powder from grinding finely and can let it spoil in storage, so the mixture should be dried fully before grinding.
Swap the white pepper
How well each one fits the dish's main ingredients (mushroom, onion, mace):
- Thymefits better
- Garlicfits better
- Clovefits better
- White pepperthe original
Fit is the average pairing score against mushroom, onion, mace. Candidates are from the same food group and used in at least 100 recipes.
