Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Shchy with Sauerkraut and Fish
Ingredients
Directions
Make the stock
Pour water over fish fillet, bring to a boil and cook until done.
Simmer the soup
Remove the fish and add stewed sauerkraut, onion, and parsley to the boiling stock, and boil for 20 to 30 minutes.
3 to 5 minutes before the shchi is done, add bay leaves and browned flour with some stock mixed in.
Serve
Put chunks of boiled fish into the ready shchi and sprinkle with minced greens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sauerkraut
- Provides the sour acidity that defines the soup's flavour.
- Fish
- Supplies protein and savoury flavour to the stock and final dish.
- Flour
- Browned and stirred in, it thickens the broth slightly and adds a toasted, deeper flavour.
- Butter
- Adds richness and a rounded, savoury fat to the finished soup.
The step that matters
Adding the browned flour. Flour added directly to hot liquid clumps. Mixing it with some stock first and adding it near the end lets it disperse smoothly, thicken the broth evenly and give a toasted flavour without raw taste.
Swap the onion
How well each one fits the dish's main ingredients (fish, flour, parsley, butter):
