Why it works: Shallot and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,081 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Roast Duck
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the duck
Clean, wash, and wipe the duck carefully.
Mix the minced shallot and sage with the usual dressing and stuff the duck with the mixture.
Sew up the duck.
Reserve the giblets for gravy.
Roast
Roast the duck at 400°F (200°C) for about 1 hour, basting well.
Make a crust with flour and water and spread the crust over the duck.
Roast the duck for an additional 30 minutes.
Remove the crust to brown the duck before it is done.
Make the gravy and serve
Skim the gravy.
Chop the giblets finely and add them to the gravy with a chopped shallot and a spoonful of browned flour.
Serve the duck with currant or grape jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat and rendered fat that browns and flavors the dish.
- Shallot
- Adds a mild, aromatic onion flavor to the stuffing and the gravy.
- Sage
- Contributes an herbal, aromatic flavor that complements the rich duck meat.
- Flour
- Forms a crust that helps protect the duck and encourages browning when removed.
The step that matters
Remove the crust to brown the duck before it is done. Timing matters: removing the crust too early leaves the skin pale, while removing it too late can overbrown or dry the surface before the interior is cooked through.
Swap the currant
How well each one fits the dish's main ingredients (shallot, sage, flour):
- Lemonfits better
- Limefits better
- Raisinfits better
- Currantthe original
Fit is the average pairing score against shallot, sage, flour. Candidates are from the same food group and used in at least 100 recipes.
