Thanks to Tony's link in the discussion section, I've managed to find the same product on Ocado - they're calling them pastry crowns (it's the same product as on the French site).

I don't think there's any particular need to translate the word "apéritifs" literally here (i.e. by including a reference to snacks), as I think it's clear enough from the surrounding context.

Hope it helps

"Corolla" is due to the shape of the mould.

I have entered first what the French mean by "corolla" and then what the English call "corolla". In the second link below you will find "tartlets" or "tarts" on the right column but you will find other names (cups, parcels) depending on the shape of the filo pastry.

French term (edited): petites corolles apéritives

I think you can retain the FR shape reference.

French term (edited): corolle apéritive

Unless your text goes on to discuss them in greater detail later, I really think all that is needed is a lightweight term that conveys the notion of 'gourmand, raffiné, ...' — I can't see there is anything here that requires too much detail, and it would certainly be better to avoid adding detail that is inaccurate.

I did rather like the alliteration of my 'filled filo flowers', but I accept that it is probably hardly really appropriate here, especially as it misses out the 'apéritif' aspect — and filled flower-shaped filo canapés' doesn't have quite the same ring about it!

Consider also the possibility of 'gourmet nibbles' — although on the face of it 'nibbles' might be considered rather down-market for oh-so-posh 'canapés', in actual fact by a kind of inverted snobbery, it could even work quite well — esepcially with the delicious counterpoint with 'gourmet'!
