Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Irish Stew
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Brown the meat
Heat the oil in a large pot over medium heat.
Add the meat and brown on all sides.
Stir in the onion and cook until softened.
Simmer and serve
Add the potatoes, carrots, and broth.
Season with salt and pepper.
Bring to a boil, then reduce heat and simmer for 1.5 to 2 hours until meat is tender.
Garnish with fresh parsley before serving.
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
- Lamb or beef
- Provides the main protein, which becomes tender through long, slow simmering.
- Potatoes
- Break down slightly as they cook, thickening the stew and adding body.
- Carrots
- Add natural sweetness and firm texture that holds up during long simmering.
- Onion
- Softens and releases sugars, building a savory base for the stew.
- Beef or lamb broth
- Provides the liquid that cooks the vegetables and carries savory flavor throughout.
The step that matters
Browning the meat. Searing meat over medium heat on all sides creates browned flavor through the Maillard reaction. Crowding the pot or skipping this step leaves the meat steaming, which gives a flatter, greyer taste in the finished stew.
Swap the onion
How well each one fits the dish's main ingredients (lamb, potato, carrot, beef, pepper, parsley):
- Parsnipfits better
- Tomatofits about as well
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against lamb, potato, carrot, beef, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
