This is the first time I heard about this. I will try to find out more on this. Really weird.
Actually, I think this might interest someone who thinks of bringing home stuff from France. It’s true that I’ve never thought of bringing fish conserves to friends.
Maybe it’s this one you should buy?
I think I like the one I like in belle iloise was sardine in olive oil. Good quality fish, but then I think you can find it rather easily in a good grocery store with other good brands too.
