Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Omelet
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.
Beat the egg whites until stiff peaks form.
In a separate bowl, beat the yolks until light and thick.
Add 2 tablespoons of milk, ½ teaspoon salt, and a dash of white pepper to the yolks; mix thoroughly.
Gently fold the beaten egg whites into the yolk mixture.
Heat a buttered pan and pour in the egg mixture, spreading it evenly.
Let it cook for about 2 minutes over moderate heat.
Transfer the pan to a 350°F (175°C) oven to cook the top until a knife inserted in the center comes out nearly clean.
Fold the omelet in half over the Spanish filling, reserving some filling for the top.
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.
