Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; parboiling firms them so they hold their shape when cut and fried.
- Egg yolk
- Binds the bread crumbs to the surface of each piece so the coating stays on during frying.
- Fine bread crumbs
- Form a crisp, golden coating that browns in the hot fat.
- Dripping
- Hot fat carries heat to the coating, driving browning and crispness.
The step that matters
Frying in hot dripping. The fat must be hot enough to brown the crumb quickly. If it is too cool, the coating absorbs grease and turns soggy before it crisps.
Swap the parsley
How well each one fits the dish's main ingredients (egg, bread, mushroom, ketchup, butter, anchovy, sauce):
- Capersfits better
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
Fit is the average pairing score against egg, bread, mushroom, ketchup, butter, anchovy, sauce. Candidates are from the same food group and used in at least 100 recipes.
