Why it works: Peas and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,016 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Ribs of Lamb
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare and roast
Preheat the oven to 350°F (175°C).
Season the ribs of lamb with salt and pepper.
Roast the lamb in the oven for about 2 hours or until tender.
Boil the vegetables
Boil the peas and potatoes until cooked through.
Serve
Serve the lamb with peas, potatoes, fruit tart, and custard.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ribs of lamb
- Fat and connective tissue soften during long roasting, keeping the meat moist and tender.
- Potatoes
- Starch cooks soft and absorbs liquid, giving the plate a filling, tender base.
The step that matters
Roast until tender. Connective tissue in lamb ribs breaks down into gelatin only with sustained heat, so pulling the meat early leaves it chewy. Check tenderness rather than relying only on the clock.
Swap the peas
How well each one fits the dish's main ingredients (lamb, pepper, potato):
- Beansfits better
- Chickpeafits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against lamb, pepper, potato. Candidates are from the same food group and used in at least 100 recipes.
“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.
