Sardines

can i ask for mackerel recommendations in this channel?

Nuri (two varieties, small whole and filets, both are good)
Minerva (spiced "com pickles")
Mouettes d'Arvor (cool flavors: mustard, seaweed, citrus)
Patagonia (also cool flavors: paprika, lemon, garlic)
King Oscar (great "grocery store" brand)

worth a shot, even if it's for the halibut

I’ve been pleased with quality and price from King Oscar.
