Why it works: Mushroom and thyme match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 2,557 recipes mention both. Both carry methyl 2-methylbutyrate, which smells apple, fatty. The science ↓
The recipe
Ingredients
Directions
Prepare the base
Pour just enough water into the stockpot to start the onions cooking.
Add the onion, leek top, garlic, shiitake mushrooms, and salt.
Give the vegetables a stir, then cover the pot and cook gently over medium heat for 15 minutes.
Simmer and strain
Add the remaining ingredients and cover with 9 cups cold water.
Bring the stock to a boil, then simmer, uncovered, for 1 hour.
Pour the stock through a strainer, pressing as much liquid as you can from the vegetables, then discard them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried shiitake mushrooms
- Provide concentrated savory, umami flavor that deepens the stock as they soften and release their juices.
- White mushrooms
- Add fresh mushroom flavor and body to the stock during simmering.
- Yellow onion
- Builds sweetness and savory depth as it cooks slowly at the start.
- Carrots
- Add natural sweetness and a rounder background flavor to the stock.
The step that matters
Cook the vegetables gently before adding water. Cooking the onion, leek and mushrooms slowly in a covered pot draws out their moisture and sugars without browning. Gentle heat builds a sweeter, more rounded base than rushing the process would.

Fit is the average pairing score against onion, garlic, shiitake, mushroom, carrot, parsley, thyme. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
