Why it works: Capers and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 379 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Capers Pickled in Vinegar
Ingredients
Directions
Prepare
Select small capers of the same size, discarding any that are developed.
Remove the stems from the capers and place them in jars or bottles.
Pickle and store
Cover the capers with cold, boiled vinegar.
Add a sprig of tarragon to each bottle for flavor, if desired.
Seal the bottles tightly and store them.
After three to four weeks, the capers will be ready to use.

What each ingredient does
- Small capers
- Provide the main flavor and texture; uniform size makes them pickle evenly.
- Cold, boiled vinegar
- Acts as the pickling liquid that preserves the capers and gives them their sharp acidity.
The step that matters
Covering the capers with cold, boiled vinegar. The capers must stay fully submerged in the vinegar. Exposed capers can spoil and mold, while a properly sealed, acidic brine keeps them preserved and firm during the weeks of pickling.
