Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Baked Shad
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the shad
Wash the shad in cold water and dry it off.
Fill the shad with stuffing, leaving room for it to swell, then sew it up with a small cord.
Sprinkle salt and pepper on the shad and dredge it with flour.
Bake and make the gravy
In a fish pan, heat the butter and lard until hot enough to brown.
Lay the fish in the pan and bake in a 400°F (200°C) oven for 45 minutes, basting often.
Add hot water, anchovy sauce, and tomato ketchup to the pan.
Boil the mixture for 1 minute, stirring from the bottom.
Pour the gravy into a dish.
Carefully cut and remove the cord from the fish.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Shad
- The main fish, whose flesh cooks through and becomes flaky in the oven.
- Flour
- Dry coating that helps the fish brown and gives the pan juices some body.
- Butter
- Fat that browns the fish surface and adds richness and aroma to the pan.
- Lard
- Fat with a high smoke point that helps the fish brown in the hot pan.
- Tomato ketchup
- Adds sweetness and acidity to the gravy, balancing the rich fat.
- Anchovy sauce
- Adds savory depth to the gravy through its salty, umami flavor.
The step that matters
Heating the butter and lard until hot enough to brown. The fat must be hot before the fish goes in, so the surface sears and browns rather than steaming. Starting in cool fat leaves the skin pale and can make it stick.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, flour, butter, anchovy, sauce, ketchup):
- Shallotfits better
- Capsicumfits better
- Horseradishfits better
- Tomatothe original
Fit is the average pairing score against pepper, flour, butter, anchovy, sauce, ketchup. Candidates are from the same food group and used in at least 100 recipes.
