How long do spicy pickled red onions last?
Store in an airtight jar in the refrigerator for up to 2 weeks. They develop deeper flavor after 24 hours.
Can I make this recipe less spicy?
Remove the habanero seeds before slicing, or substitute with a milder jalapeño. You can also reduce the quantity by half.
Do I need to cook the onions?
No. Pour boiling water over the sliced onions to soften them slightly, then drain and combine with the vinegar and lime mixture.
What dishes pair best with these pickled onions?
They work well on tacos, ceviche, tostadas, quesadillas, nachos, and grain bowls for added tang and heat.
Can I substitute the habanero?
Yes. Jalapeño or serrano peppers work well, though they'll be less intense. Thai chilies add similar heat with different flavor.
