Herb Vinegar Pickled Red Onions with Mustard Seed

Preserves of the onion variety really get me excited. They are super tasty and are good on pretty much anything. Might I remind you of the infamous black onion relish? (ps if you haven’t made it yet, you should really get on it — it’s pretty flippin’ awesome) Accompanied by some homemade ricotta cheese on some toasted bread, it’s absolutely divine!

So one of my favorite ways to preserve onions is a simple quick pickle. A little vinegar, a touch of sugar, some Dijon mustard, and I’m practically eating them out of the jar. So I figured why not make some shelf stable vinegared onions so I’ve always got some on hand?

I started with the basic idea of a quick pickled onion and basically expanded it into something new, interesting, and flat out delicious. Plus they are probably the cutest preserves I’ve made to date. Who doesn’t love a jar of pink pickled goodness, am I right?! Plus I got to use my herbed vinegar –remember that Thrifty Tip?

I totally cannot wait to crack these open at my next dinner party. Alongside some deviled eggs and some cured meat…fab!

Get on it, like now.
