Sweetbreads with Tomato Gravy

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare and boil

  1. Season sweetbreads with black pepper to taste.

  2. Boil sweetbreads for 30 minutes.

Make the gravy

  1. Thicken the gravy with a little browned flour and add butter.

  2. Let it stew for a few minutes.

Bake and serve

  1. Transfer to a 400°F (200°C) oven to brown.

  2. Remove sweetbreads to a dish.

  3. Pour in less than a pint of stewed tomatoes seasoned with salt, pepper, and butter, and bring to a boil.

  4. Pour over the sweetbreads and serve hot.

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

What each ingredient does

Sweetbreads
The main protein, firmed by boiling before it is browned in the oven.
Browned flour
Thickens the gravy and adds a toasted, nutty flavor.
Butter
Adds richness and a smooth mouthfeel to the gravy.
Stewed tomatoes
Provide acidity and moisture that give the gravy its tangy flavor.

The step that matters

Thickening the gravy. Browned flour must be stirred in evenly and stewed for a few minutes so its starch swells fully and the gravy thickens smoothly without raw, floury lumps or taste.

Swap the tomato

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

  1. Shallotfits better
  2. Chivefits better
  3. Capsicumfits better
  4. Tomatothe original

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