Why it works: Ketchup and sauce 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 ↓
Sweetbreads, Cradle of
Ingredients
Directions
Prepare the sweetbread
Soak the sweetbread in warm water for 2 hours.
Boil the sweetbread in water for 10 minutes to blanch it.
Cool the sweetbread in cold water.
Tear the sweetbread into neat pieces using two forks.
Roll each piece in beaten egg, then toss in bread crumbs.
Let the pieces sit for 20 minutes.
Repeat the egg and bread crumb process.
Make the sauce and fry the sweetbread
Heat the butter in a saucepan until hot.
Fry the sweetbreads in the butter until golden brown.
Remove the sweetbreads from the pan.
Brown the flour in the same pan.
Add the stock and stir until boiling.
Skim well.
Add the ketchup, Harvey's sauce, and lemon juice.
Return the sweetbreads to the sauce and stew for 20 minutes.
Make the case and serve
Cut the slice of bread, marking an inch from the edge with a knife.
Fry the bread in boiling fat until golden brown.
Remove the top of the bread and hollow out the center.
Fill with the sweetbreads and garnish with mushrooms.

Butter and flour 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
- Sweetbread
- Its tender, delicate texture is the main element of the filling.
- Eggs
- Bind the bread crumbs to the sweetbread pieces so they form a coating.
- Bread crumbs
- Form a crisp, golden coating that browns when fried.
- Butter
- Fat for frying that browns the coating and adds rich flavor.
- Flour
- Browned in the pan fat to thicken the stock into a sauce.
- Stock
- Liquid base of the sauce that the sweetbreads stew in.
The step that matters
Frying the coated sweetbread until golden brown. Coating must be fully set and evenly browned before frying; wet or loosely attached crumbs fall off and absorb excess fat, and the sweetbread must be cooked through after blanching.
