Key move

Ensure the vinegar brine is steaming hot before pouring over the sliced onions; this heat is crucial for softening them and initiating the pickling process.

The Mise en Place

5 of 6

Your prep station before cooking begins

The Aromatics (0/1)

1 wholelarge red onion(thinly sliced)

The Spice Blend (0/1)

1 tbspkosher salt

The Pantry (0/1)

1 cupvinegar (240ml)

The Finish (0/2)

1 tbspsugar(optional but helps balance)
5 goptional: 1 garlic clove, peppercorns, chili flakes, bay leaf

My onions are still hard and taste raw after sitting.

Ah, it sounds like the brine in Step 1 wasn't quite hot enough when you poured it over the onions.

These onions are mushy and the color has faded.

That can happen if the onions were cut a bit too thick initially, or if the brine boiled too aggressively for too long, making it overly hot.

Chef's Notes

Tip

For thinner slices, use a mandoline. Be careful!

Tip

Press onions down in the jar to ensure they are submerged in brine.

Serving

Delicious on tacos, salads, sandwiches, or avocado toast.

Variation

Add a pinch of red pepper flakes to the brine for a spicy kick.
