Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein, which becomes tender and firm when blanched and braised, then browned by glazing.
- Egg yolks
- Bind the mashed potatoes and enrich them, helping the mixture set firm when poached.
- Butter
- Adds richness and moisture to the mashed potatoes and keeps the mold surfaces from sticking.
- Mashed potatoes
- Form the set, soft base of the chartreuse that holds the vegetables and sweetbreads together.
- Broth
- Provides moisture for braising, keeping the sweetbreads tender while they cook.
- Tomato sauce
- Adds acidity and savory depth to the cooking liquor for the finishing sauce.
The step that matters
Poaching the chartreuse in a bain-marie. The potato and egg yolk mixture sets as it heats. Gentle, even heat in a water bath keeps it smooth and firm; overheating can make the eggs curdle and the mixture grainy.
