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

What each ingredient does

Boned leg of lamb
Forms the main meat; roasting cooks it through while keeping it juicy when rested.
Dried portobello mushrooms
Soaked to release concentrated mushroom flavor into the reserved liquid used in the sauce.
Button mushrooms
Sautéed in butter and oil to brown and add savory body to the sauce.
Blue cheese
Melts into the cream to add salty, tangy depth to the sauce.
Light cream
Adds fat and richness, giving the sauce a smooth, silky texture.
Red currant jelly
Adds sweetness and fruity acidity to balance the rich, salty cheese.

The step that matters

Heat the sauce gently after adding the bitters. Cream and blue cheese can separate or turn grainy when boiled hard, so keep the heat gentle and add the bitters just before serving so their aroma stays fresh.
