Use avocados that are not quite ripe in this recipe; pickling softens them.

How to Make It

Whisk together vinegar, 1/2 cup water, salt, mustard seeds, sugar, peppercorns, and chile de arbol, if desired, in a medium nonreactive pot. Bring mixture to a simmer over medium heat, stirring until sugar and salt dissolve, then let it cool to room temperature, about 20 minutes.
