Why it works: Parsnip and sauce work together. They rank in the top 23% of all ingredient pairs, and cooks put them together in 156 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Salt Fish and Parsnips
Ingredients
Directions
Prepare the salt cod
Wash the salt cod and soak it in cold water for 12 hours, changing the water every 3 to 4 hours.
Cover the fish with cold water and bring it to a simmer.
Cook gently for about 20 minutes, or until the fish flakes easily from the bones.
Cook the parsnips
While the fish is cooking, boil the parsnips.
If they are small, cut them in half lengthwise; if large, cut them into quarters.
Serve
Drain the fish well and place it on a hot dish.
Pour the egg sauce over the fish and garnish with the parsnips.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and sauce barely smell alike, yet cooks put them together in 10,895 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt cod
- Soaking removes salt, and gentle simmering keeps the flesh moist and flaky.
- Parsnips
- Their natural sweetness and starch give the dish a soft, tender contrast to the fish.
The step that matters
Cook gently for about 20 minutes. Simmering gently rather than boiling hard keeps the fish tender and intact, so it flakes cleanly instead of toughening and breaking apart.
Swap the parsnip
How well each one fits the dish's main ingredients (egg, sauce):
- Horseradishfits better
- Shallotfits better
- Asparagusfits better
- Parsnipthe original
Fit is the average pairing score against egg, sauce. Candidates are from the same food group and used in at least 100 recipes.
