Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a tender, sliceable structure as they cook.
- Cream
- Adds moisture and richness, keeping the custard soft rather than rubbery.
- Ham
- Contributes savory, salty flavor throughout the custard.
- Tongue
- Adds savory, meaty flavor and a more substantial bite.
- Shallot
- Adds mild onion-like aroma and savory depth.
The step that matters
Steam the cups gently. Egg proteins set at moderate temperatures. High heat or boiling water can overcook the custard, making it grainy, watery, or spongy. Gentle steam keeps it smooth and tender.
Swap the shallot
How well each one fits the dish's main ingredients (egg, cream, pepper, parsley, ham):

Fit is the average pairing score against egg, cream, pepper, parsley, ham. Candidates are from the same food group and used in at least 100 recipes.
