Spicy Pickled Onions

Spicy Pickled Onions

Thinly sliced red onions sit in a glossy, amber‑gold brine, speckled with bright red pepper flakes and a hint of smoked paprika. The onions remain crisp yet softened by the vinegar, their sharpness mellowed by a touch of honey and a splash of lime juice. This bright, crunchy garnish adds tang, heat, and a pop of color to tacos, salads, and grilled meats.
