Why it works: Shiitake and mushroom match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 552 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
The recipe
Ingredients
Contains: wheat, soy (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the mushrooms
Place shiitake mushrooms in medium bowl and add boiling water. Cover with a small plate and set aside 30 minutes.
Drain mushrooms, reserving soaking liquid. Remove and discard stems from shiitake mushrooms, then slice mushrooms into strips and set aside.
Place mushroom soaking liquid into measuring cup, adding water if necessary, to make 2 cups. Add soy sauce to mushroom liquid and set aside until ready to use.
Make the gravy
In medium saucepan, heat oil over medium heat.
Add onion and cook, stirring often, until golden brown, about 9 minutes.
Add sugar, thyme, button mushrooms, and reserved shiitakes; cook, stirring occasionally, until button mushrooms are tender, about 4 minutes.
Add flour and cook, stirring occasionally, 1 to 2 minutes.
Whisk in reserved mushroom liquid and cook, stirring continuously, until thickened, 5 minutes.
Stir in parsley, and add salt and freshly ground pepper to taste.

Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried shiitake mushrooms
- Provide the main earthy, savory flavor and chewy texture in the gravy.
- All-purpose flour
- Thickens the liquid into a gravy as it cooks with the fat and mushroom liquid.
- Mushroom soaking liquid
- Supplies concentrated mushroom flavor and the liquid base of the gravy.
- Onion
- Browns and sweetens as it cooks, adding depth to the gravy's flavor.
- Button mushrooms
- Add moisture and body, softening into the gravy's savory base.
The step that matters
Cooking the onion until golden brown. Browning the onion slowly develops sweet, deep flavors through the Maillard reaction and caramelization. Pale onions leave the gravy tasting flat, so keep the heat moderate and stir often to avoid scorching.

Fit is the average pairing score against shiitake, mushroom, sauce, olive, sugar, thyme, flour. 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).
