Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein, which turns tender and delicate when partly boiled and then gently stewed.
- Cream
- Adds richness and body to the white gravy, giving it a smooth, velvety texture.
- Flour
- Thickens the butter and cream into a gravy that clings to the sweetbreads.
- Butter
- Adds fat for richness and flavour, and helps the crumbs brown if used.
The step that matters
Half boil the sweetbreads. Boiling firms the outer membrane and sets the texture so the sweetbreads hold their shape during stewing or browning. Cooking them too long toughens the delicate meat, so the boil should be brief.
Swap the nutmeg
How well each one fits the dish's main ingredients (pepper, cream, flour, butter, mushroom):
- Nutmegthe original
- Thymefits about as well
- Parsleyfits about as well
- Tarragonfits less well
Fit is the average pairing score against pepper, cream, flour, butter, mushroom. Candidates are from the same food group and used in at least 100 recipes.
