Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Irish Stew
Ingredients
Directions
Make the broth
In a kettle, combine the meat and enough water to cover it.
Add the parsley, sliced onions, and coarse sea salt.
Boil for 15 minutes, allowing half of the water to evaporate.
Can and process
Can the meat, covering it with the broth.
Seal airtight and process: 1 lb cans for 1 hour 20 minutes at 238°F, 2 lb cans for 2 hours at 238°F, and 3 lb cans for 2 hours 15 minutes at 240°F.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Provides the main body; long cooking breaks down connective tissue, so the meat turns tender and flavours the broth.
- Sliced onions
- Add sweetness and aroma as they soften and release their flavour into the broth.
- Parsley
- Adds a fresh, herbal aroma to the broth.
The step that matters
Sealing and processing the cans. Meat is a low-acid food, so it must be processed for the full stated time at the stated temperature for its can size. Underprocessing can leave heat-resistant bacterial spores alive, which is a serious safety risk in sealed food.
Swap the parsley

Fit is the average pairing score against meat, onion. Candidates are from the same food group and used in at least 100 recipes.
