Onion-Cilantro Relish

This simple relish turns up in Mexico wherever you find barbacoa (see for a description), grilled fish, or grilled meats. I love the way the relish launches a triple assault on your tongue: the pungency of the onion, the peppery bite of the radishes, and the aromatic punch of fresh cilantro. By the way, the cilantro has a neutralizing effect on the onion; you’re less likely to get “onion breath” when you eat the two ingredients together.
