Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- The main protein, whose rich fat renders and keeps the meat moist as it roasts.
- Butter
- Adds fat that helps the skin brown and keeps the surface from drying out.
- Flour
- Dusted lightly on the bird, it helps the skin brown and crisp.
- Onion
- Flavours the basting liquid with a mild, savoury aroma.
- Lemon
- Adds bright acidity and aroma when squeezed over the cooked meat.
The step that matters
Hold off basting for the first 5 minutes. Opening the oven or spooning liquid over the bird early lets heat and juices escape, which slows the skin from setting and browning. Waiting until the first 5 minutes are up keeps the juices in and gives a crisper surface.
