dish was originally intended for the poor but now only the rich have access to this dish

eel fry 

 Today, they are traded in Europe around 300 to 500 € per kilo and are trafficked to Asia, where the price per kilo becomes stratospheric.

It is impossible to raise eel fry: it is assumed that they are born somewhere in the Sargasso Sea, but we have never seen an eel egg...

In the Nantes region, before becoming a delicacy and popular with gourmets, the glass eel, then abundant, was a poor man's dish: the Loire was still teeming with it in the 60s before pollution decimated them.

My grandmother would also say to my grandfather when he brought it back to her: "Again! But that's for the bells!"
