Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Green Peas a LA Francaise
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Place the shelled peas, onions, and shredded bacon in a thoroughly buttered paper bag.
Season with salt, pepper, and powdered sugar.
Add ½ to ¾ cup of water, then close the bag and fasten it with clips.
Bake and serve
Place the bag on a wire grid and cook in the oven for 30 to 35 minutes.
Once cooked, transfer the peas to a hot dish and sprinkle with chopped parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish and soften into a tender, sweet vegetable.
- Onions
- Soften as they cook, adding sweetness and a mild aromatic flavor to the peas.
- Streaky bacon
- Renders fat into the peas and adds savory, smoky flavor as it cooks.
- Powdered sugar
- Adds a little sweetness that balances the savory bacon and seasoning.
The step that matters
Closing the bag tightly. The sealed bag traps steam so the peas cook gently in their own moisture and the added water. If the bag leaks or is left open, steam escapes, the peas can dry out, and the cooking becomes uneven.
Swap the peas
How well each one fits the dish's main ingredients (onion, pepper, sugar, parsley):
- Black-eyed peafits better
- Chickpeafits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against onion, pepper, sugar, parsley. Candidates are from the same food group and used in at least 100 recipes.
