Haha, skip the onions. It's still good.

I had so much on that slice of bread with lard. And also because I like onions, not gonna lie.

If you are Swedish then you are familiar with herring 🙂

I bought the vinegar marinated ones in Ikea. I know, Ikea is perhaps not gourmet food but I liked them a lot!

Herring in oil is a Polish thing, usually for holidays like Christmas or Easter. I just bought herring filets, cut them is smaller pieces, rinsed them a few times, soaked in milk, dunked in oil, added onions, and left in fridge for 2 days. That's the basic recipe, though there are variations to it.
