I made these pickled onions as a side for the black bean/cochinita pibil meal. I remembered the cochinita pibil tacos/burritos at El Chilito and new that part of what made those divine were the purplish onions on top that weren't strong at all.
Make these a day ahead of when you want to serve them to let the flavors soak into the onions and deepen. These are great on pulled pork, and black beans and rice. I am also thinking about using these to make leftover fish tacos with the leftover fish I made from the other night.
