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 ↓
Roast Leg of Mutton
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Have the bone cut short and wipe the leg of mutton with cold water.
Dredge the meat with flour, coarse sea salt, and black pepper.
Roast
Place in a hot oven at 400°F (200°C) for 15 minutes.
Add 1 cup of hot water to the pan and baste frequently.
Cook for 10 minutes per pound for rare, or 15 minutes per pound for well done.
Serve
Garnish the end of the bone with a paper frill or a bunch of watercress or parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main cut of meat, providing the flavour and texture of the whole dish.
- Flour
- Coats the surface, helping the outside brown and form a crust during roasting.
- Hot water
- Added to the pan to create steam and moisture that keeps the meat from drying out.
The step that matters
Cooking time per pound. Roasting time depends on weight and the doneness you want, so a cook who misjudges the weight or time can end up with meat that is overcooked or underdone. Checking the meat's internal temperature is a reliable way to confirm doneness.
“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.
