I still think about those spicy onions today. This pickled red onion takes a head nod from those onions.

How to Pickle Red Onions for Tacos
When making anything pickled there are a few kitchen tools that will make your life easier. First, an adjustable mandoline is a must-have. I actually like the ones with a handle better than one that is self-standing. Then you will also want a bowl that the mandoline can lay across while you slice. Finally, you will need ball jars or hinged jars to the refrigerator the onions in.
Begin by slicing your onions. I used the middle setting of the mandoline to slice the onions straight into a bowl. When the onions are sliced move to the radishes. Make the radishes even thinner sliced. Slice them into the bowl as well. Finally, if you are using jalapenos, adjust the mandoline to the largest slice and slice your pepper. You can just slice them with a knife as well as peppers don't slice great in the mandoline.
Layer the onions, radishes, and peppers into the jars of choice to begin creating the pickled red onion recipe. Fill the jars to the brim. Next, cut a lime in half and squeeze the juice over the onions. Add the salt, honey, and peppercorns to the top of the onions.
Pour vinegar into the jar until half full and then finally fill to the top with water. Place the lid on the jar and shake the contents to get the honey, salt, and peppercorns throughout the entire jar.
Place the pickled red onions in the fridge for 24 hours and then enjoy. I know you want to try these pickled onions. It is worth it. Go ahead and try them. Here are some great recipes you could add these onions to for even more flavor in already great recipes.
