Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Fresh Herrings Baked
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the herrings in clear spring water and clean them thoroughly.
Drain the herrings and place them in a baking dish without wiping.
Season and bake
Season with salt and pepper, then sprinkle the chopped onions, parsley, and thyme on top.
Pour equal parts vinegar and small beer over the herrings.
Cover the dish and bake in a slow oven at 300°F (150°C) for one hour.
Serve
Serve cold, keeping them in the pickle for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Provide the oily, firm flesh that is the main body of the dish.
- Onions
- Add sweetness and aroma that mellow as they cook in the liquid.
- Vinegar
- Adds acidity that sharpens flavor and helps preserve the fish in the pickle.
- Small beer
- Adds a mild malty depth that balances the sharpness of the vinegar.
The step that matters
Covered slow baking. Baking gently at a low temperature with the dish covered cooks the fish evenly so it becomes tender without drying or breaking apart. Too much heat can toughen the flesh and dry it out.
Swap the onion
How well each one fits the dish's main ingredients (pepper, parsley, thyme, vinegar, beer):
- Capsicumfits better
- Shallotfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against pepper, parsley, thyme, vinegar, beer. Candidates are from the same food group and used in at least 100 recipes.
