Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- Forms the main body of the dish, becoming firm and flaky once cooked and cooled.
- Cider vinegar
- Acidity that sours and preserves the cooked fish as it marinates in the refrigerator.
The step that matters
Let the shad cool completely before seasoning and covering it with vinegar. Adding vinegar to warm fish can break it into pieces and make it mushy, and cooling lets the fish firm up so it holds its shape while it pickles.
Swap the allspice
How well each one fits the dish's main ingredients (pepper, cider, vinegar):
- Allspicethe original
- Tarragonfits about as well
- Clovefits about as well
- Thymefits about as well
Fit is the average pairing score against pepper, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
