Why it works: Leek and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Gravy for Fish or White Sauce
Ingredients
Directions
Make the base
Boil the ingredients and skim off any impurities.
Season with onions, leeks, celery, carrots, turnips, herbs, cloves, allspice, and salt.
Let it stew for 4 hours, then strain and set aside.
Make the strong gravy
For strong gravy, layer bacon, beef, carrot, onion, bread, herbs, mace, cloves, pepper, and anchovy in a stewpan.
Cover and cook on low heat for 5-6 minutes.
Pour in 1 quart of the prepared gravy, cover, and let it simmer until reduced by half.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Build the savory, sweet base flavor of the stock.
- Celery
- Adds aromatic depth to the stock as it simmers.
- Anchovy
- Adds savory depth that rounds out the gravy's flavor.
- Bacon
- Releases fat and smoky, savory flavor into the gravy.
- Beef
- Contributes meaty richness and body to the strong gravy.
The step that matters
Reducing the strong gravy by half. Simmering slowly concentrates flavor and thickens the liquid through evaporation. Too high a heat or too long can over-salt or scorch the gravy, so keep it at a gentle simmer and watch it closely.
Swap the onion
How well each one fits the dish's main ingredients (leek, celery, carrot, turnip, clove, allspice, beef):

Fit is the average pairing score against leek, celery, carrot, turnip, clove, allspice, beef. Candidates are from the same food group and used in at least 100 recipes.
