Last winter, I had friends coming over to my place for brunch. I served them some avocado toasts with soft-boiled eggs and cilantro. When I grabbed my pickled onions jar to put some over, they were funnily impressed ! They though it was fancy and gourmet.
This is funny to me, because pickled onions are the simplest condiment to make. And you only need 3 ingredients besides water and salt ! You can customize their basic version if you want and add things like mustard seeds or bay leaves, but the plain ones are great too.
You don’t want to throw em everywhere just because they’re pretty ! I add some to a dish when it seems relevant, to offset a sweet flavour or a quite high fat content. They also give a nice kick to raw vegetables, say in salads or sandwiches.
Get ready to have your guests impressed though. It never hurts !
