Why it works: Onion and jalapeno are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 2,250 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Nicaraguan Pickled Onions
Ingredients
Directions
Prepare
Handle fresh chile with care, slice jalapenos very thinly.
Combine vinegar, water, sugar, and salt, whisk until sugar and salt have dissolved.
Pickle and store
Add onions and jalapenos to pickling mixture, store in refrigerator for 2-3 days, stirring occasionally.
Onions will keep for several weeks in the refrigerator.
These onions are served as table condiments for grilled beef dishes. You may increase the heat by adding more jalapenos.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White onion
- Forms the bulk of the dish and turns mild and tender as it soaks in the pickling liquid.
- White vinegar
- Provides the acidity that pickles the onions and gives them their sharp, tangy flavor.
- Jalapeno chile
- Adds heat and fresh pepper flavor that spreads through the pickling liquid.
The step that matters
Dissolving the sugar and salt in the vinegar mixture. Whisking until the sugar and salt fully dissolve ensures the brine is evenly seasoned, so every onion slice and chile pickles with the same balance of salt, sweetness and acid.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, sugar, jalapeno):
- Mustardfits better
- Cucumberfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against vinegar, sugar, jalapeno. Candidates are from the same food group and used in at least 100 recipes.
