Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring roes
- Provide the rich, creamy texture and savory flavor that define the dish.
- Mushrooms
- Add moisture and earthy savoriness when fried, softening and browning in the pan.
- Fried bread or toast
- Gives a crisp, absorbent base that holds the mushrooms and roe.
The step that matters
Poaching the herring roes. Roe is delicate and can overcook quickly, turning firm and grainy. Keeping the time brief in simmering water sets them gently while staying tender.
Swap the parsley
How well each one fits the dish's main ingredients (roe, mushroom, pepper, bread):
- Thymefits about as well
- Parsleythe original
- Marjoramfits about as well
- Garlicfits less well
Fit is the average pairing score against roe, mushroom, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
