Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bechamel Sauce
Ingredients
Directions
In a stew pan, melt 1 ounce of butter and sauté the sliced onion without browning.
Add the meat and bones, cover with water, and skip the browning stage.
Prepare a clear consomme by adding 1 teaspoon of powdered sugar and all the vegetables.
Skim the broth carefully and strain it for later use.
In a saucepan, melt ¼ pound of butter and gently fry the sliced carrot and onion for 10 minutes.
Before they color, add 2 ounces of flour and stir for 5 minutes.
Gradually add the clear broth, ½ cup of cream, chopped mushrooms, salt, and pepper.
Bring to a boil, then simmer slowly for 1 hour, skimming off any fat.
Strain the sauce into another saucepan and keep it warm in a bain-marie.
Before serving, stir in an additional ½ cup of cream.
