Elimination cooking can taste a little flat after a while, and a bright, tangy condiment is one of the simplest ways to bring a plate back to life. These pickled onions take about ten minutes of hands-on work and no cooking at all. You slice, you pour warm brine over, you wait. A jar in the fridge means every bowl of greens, every plate of brisket, every simple protein gets a quick lift whenever you want one.
Red onions bring their own gentle nourishment, and the vinegar brine adds a clean, bright tang that many people find supports digestion before a meal. There is no sugar here and nothing excluded, just onion, vinegar, a little cinnamon and dill, and salt. This is a small, easy thing that makes the larger work of eating well feel less monotonous, which matters when the protocol is long.
Pack the onions into a jar you like and watch them turn a beautiful pink as they steep. Keep them where you will see them, and let them make your plates feel cared for.
Ingredients
- 2 large red onions, thinly sliced
- 1 1/4 cups apple cider vinegar (1 cup standing in for white wine vinegar, plus the original 1/4 cup)
- 1/2 cup boiling water
- 1 tsp cinnamon
- 1 tsp dried dill (dill weed or leaf)
- 1 tsp sea salt
Method
Pack the thinly sliced red onions into a clean jar or bowl.
Stir the apple cider vinegar, boiling water, cinnamon, dried dill, and salt together until the salt dissolves. Pour this warm brine over the onions so they are fully submerged. Press them down if any float.
Let the onions steep at room temperature for at least 30 minutes for a quick pickle, or cover and refrigerate overnight for a deeper, softer result. Keep them covered in the fridge and use the brine as part of the flavor when you serve them.
