I love mackerel, especially grilled with a good rub of salt. There’s a dude in Berlin who grills a variety of whole fish & filets at his stand: trout, mackerel, zander, squid. I almost always get a whole mackerel… and when I get a whole trout instead, I am inevitably disappointed.
He serves the filets and whole fish with homemade horseradish dip, an herb dip, lemon & red onion. It’s one of my favorite lunches in town to have (and thankfully, the pad we stay in usually is near one of his market locations 
I also absolutely love smoked mackerel, which is great served with cranberry-horseradish. I swearz.
