Why it works: Summer savory and capers share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and cooks put them together in 4 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Roast Spare Rib

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 rib

  1. Preheat your oven to 400°F (200°C).

  2. Season the spare rib with coarse sea salt, black pepper, and summer savory.

Roast and make the sauce

  1. Roast the spare rib in the oven until thoroughly well done.

  2. In a saucepan, melt the butter and mix in the flour until smooth. Gradually pour in boiling water until the sauce thickens.

  3. Stir in the chopped hard boiled egg and capers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Spare rib
Provides the main protein, which becomes tender and browned through roasting.
Butter
Adds richness and fat to the sauce base, carrying flavor.
Flour
Thickens the butter into a roux that gives the sauce body.
Hard boiled egg
Adds soft texture and mild richness to the finished sauce.
Capers
Add acidity and a salty, sharp bite that cuts the richness of the sauce.

The step that matters

Mixing the flour into the butter before adding water. Cooking the butter and flour together forms a roux that thickens smoothly. Adding the water gradually, while stirring, keeps lumps from forming as starch swells and the sauce thickens.

Swap the capers

How well each one fits the dish's main ingredients (pepper, summer savory, butter, flour, egg):

  1. Parsleyfits better
  2. Nutmegfits better
  3. Thymefits better
  4. Capersthe original

Fit is the average pairing score against pepper, summer savory, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
