Why it works: Tomato and pepper match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 17,913 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Cut rounds of bread and sauté in butter until brown on both sides.
Fry the thick slices of tomatoes in hot butter until cooked.
Dip the green pepper strips in boiling water, then drop into ice water.
Place a slice of tomato on each slice of bread, season well, and sprinkle with green pepper.
Top with another slice of tomato.
Garnish with parsley and pass the hard-cooked egg yolk through a ricer.
