Why it works: Jalapeno and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 561 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Oven350 °F
Timeabout 35 minutes

Ingredients

Directions

Prepare

  1. Preheat oven to 350 °F. Oil a 9 × 13‑inch baking dish.

  2. To roast chilies, place them in a preheated 450 °F oven on a cookie sheet, turning after 10 minutes, and continue roasting until the skins blister and blacken in spots.

  3. Or, place on a broiler pan and broil about 5 to 6 inches from the heat source, turning often, until the skin is charred on all sides.

  4. Or, hold over a gas burner, turning until all sides are charred.

  5. Place the chilies in a bag or covered bowl for about 10 minutes; the skin should peel right off.

Assemble and bake

  1. Stuff each chile with a cheese stick and place it in the baking dish.

  2. Beat together the eggs, jalapeno, flour, salt, and milk in a bowl; pour over the chilies and sprinkle cheese over the top.

  3. Bake for about 35 minutes, or until golden brown. Cool for 10 minutes before serving.

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

What each ingredient does

Eggs
Set the custard and bind the casserole into a sliceable structure as they cook.
Monterey jack cheese
Melts into the filling, adding richness and a creamy texture around the chilies.
Flour
Thickens the egg and milk mixture so it holds together rather than running out.
Milk
Adds moisture and loosens the egg mixture into a smooth, pourable custard.
Cheddar cheese
Melts over the top and browns, adding flavor and a golden crust.

The step that matters

Charring and peeling the chilies. Blistered, blackened skin loosens so it peels off cleanly after steaming in a covered bowl. Leftover skin can taste bitter and become tough in the finished casserole.

Swap the jalapeno

How well each one fits the dish's main ingredients (cheese, egg, flour, milk, cheddar cheese):

  1. Jalapenothe original
  2. Nutmegfits about as well
  3. Cinnamonfits less well
  4. Turmericfits less well

Fit is the average pairing score against cheese, egg, flour, milk, cheddar cheese. Candidates are from the same food group and used in at least 100 recipes.
