Spicy Pickled Onions

Pika is a simple condiment made of finely chopped onions—very similar to what Dutch people eat atop raw herring—combined with scotch bonnet or habanero peppers and white vinegar. This funky, flavorful condiment is great on any number of dishes, but a warning: It is quite spicy. Reduce the number of chiles or deseed them for a milder version.
