Why it works: Capers and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sardine Fritters
Ingredients
Directions
Cut the French rolls into moderately thick slices and place them in a deep dish.
Beat the eggs with the milk and pour over the bread slices. Let soak well.
Melt the butter in a saucepan, then add the yolks of the hard-boiled eggs, parsley, tarragon, and burnet. Stir over heat for 5-6 minutes.
Add the capers, lemon juice or vinegar, gravy, salad oil, and mustard. Thicken with grated breadcrumbs and mix well.
Skin and bone the sardines, mince them, and mix into a smooth paste.
Fry the soaked bread slices in butter until delicately browned, then drain them.
Spread the sardine paste over the fried bread slices and arrange them in a circle on a hot dish.
Fill the center with poached eggs and pour the sauce over. Place in a hot oven for 2-3 minutes, then serve.
