Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Krémeskys of Sweetbread a LA Russe
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Soak the sweetbreads in cold water for a few hours, then boil until tender.
Remove the membranes and cut into small pieces.
In a pan, melt butter and stir in flour to make a roux.
Gradually add milk, stirring until thickened.
Mix in egg yolks, sweetbreads, salt, and pepper.
Pour the mixture into a baking dish and bake at 350°F (175°C) until set.
Garnish with chopped parsley before serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
