Why it works: Flour and watercress match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 340 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
A Shoulder of Lamb
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
Preheat your oven to 400°F (200°C).
Season and roast
Season the shoulder of lamb with butter, flour, and coarse sea salt.
Roast the lamb for 20 minutes.
Baste the lamb occasionally during roasting.
Serve
Garnish with watercress before serving.

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
- Lamb shoulder
- Forms the main body of the dish, providing the meat that is roasted and served.
- Butter
- Adds fat that carries flavour and helps the surface brown and stay moist during roasting.
- Flour
- Helps the seasoning coat the surface and encourages browning on the outside of the meat.
The step that matters
Baste the lamb occasionally during roasting. Spooning the fat and juices over the meat keeps the surface from drying out and helps it brown evenly, while the interior cooks gently.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
