I was grabbing a coffee in my local coffee shop which is also a bakery/delicatessen and I saw pickled onions in a jar so I thought I'd give them a try. They were so good. The ingredients were listed on the side and I thought to myself, I could make these and so I did. Sorry little deli but I'll never make store bought again. I put them in everything, salads, sandwiches, garnishes, burgers. They add a bit of crunch and a flavour punch. So so good and dead easy to make.
Makes a jar
400ml apple cider vinegar
2 tbsp. sugar or maple syrup
1 tbsp. yellow mustard seeds
1 tbsp. black mustard seeds
1 tbsp. coriander seeds
4 small red onions (you can use large if you like but they are less elegant when sliced)
Salt & black pepper to season
Sterilise the jar that you plan to use. Here's instructions on how to do that: https://www.bbcgoodfood.com/videos/techniques/how-sterilise-jars-video
Thinly slice the onions. If you had a mandolin for this, that would be perfect.
Add the apple cider vinegar, sugar and mustard seeds to a medium sized bowl and stir until the sugar is dissolved.
Add the rest of the ingredients and stir through.
Add all the ingredients into the jar and you're done.
They should last 2-3 weeks in the fridge. They would make a nice little foodie gift for Christmas.
