Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Roast Turkey
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the turkey
Dress the turkey 2-3 days in advance, but do not salt until the evening before roasting.
Rub 2 tablespoons of salt inside the turkey and 1 tablespoon in the breast where the crop was removed.
Place a small onion inside the turkey.
Cream together the butter, flour, and egg yolk, then rub the mixture all over the turkey.
Roast
Place the turkey on a wire rack in a roasting pan and add 1 pint of boiling water.
Roast in a very hot oven at 400°F (200°C) until both sides are seared.
Bake for ½ hour on each side, then turn the turkey breast down and finish roasting.
Roast an 8-10 pound turkey for 2-2½ hours, a 12-pound turkey for 3 hours, and adjust for larger birds.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turkey
- Forms the main body of the dish, cooking through as its meat sets and browns.
- Butter
- Adds fat that keeps the skin moist and helps it brown evenly.
- Flour
- Thickens the butter paste so it clings to the skin and aids browning.
- Egg yolk
- Binds the butter and flour into a paste that adheres to the turkey.
The step that matters
Roast in a very hot oven until both sides are seared. Searing at high heat browns the skin and builds flavour through the Maillard reaction. Turning the breast down later lets the thicker meat cook through without overbrowning.
Swap the onion
How well each one fits the dish's main ingredients (turkey, butter, flour, egg):
- Shallotfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against turkey, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
