Orange Omelet

Ingredients

Directions

  1. In a bowl, beat the eggs with salt, fruit sugar, orange juice, lemon juice, and grated orange rind.

  2. Melt the butter in a skillet over medium heat.

  3. Pour the egg mixture into the skillet and cook until set, like a foamy omelet.

  4. Fold the omelet, turn it out onto a plate, sprinkle with fruit sugar, and garnish with orange sections.

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

What each ingredient does

Eggs
Set into the structure of the omelet as they cook, holding the filling together.
Fruit sugar
Adds sweetness and helps balance the citrus acidity.
Orange juice
Adds moisture and citrus flavor to the egg mixture.
Lemon juice
Adds acidity that brightens the flavor of the eggs.
Butter
Adds fat and richness and keeps the omelet from sticking to the skillet.

The step that matters

Cook until set. Eggs turn from liquid to solid as their proteins coagulate with heat. Cooking over medium heat until just set keeps the omelet tender, while overcooking makes it dry and rubbery.

Swap the orange

How well each one fits the dish's main ingredients (egg, sugar, lemon, butter):

  1. Vanillafits about as well
  2. Orangethe original
  3. Raspberryfits about as well
  4. Figfits about as well

Fit is the average pairing score against egg, sugar, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
