You can eat anything, once :) Goats routinely eat caprifigs, that's how they got their name. Gillette (Croisic), Saleeb, Enderud, Brawley, Rosso and Cordelia are the ones I know about that produce edible caprifigs. There are probably others, depending on how loose you want to be with the term, 'edible' :)
Gillette and Cordelia may be synonyms. There's a Pingo de Mel that's also listed as a synonym but it's probably not the same as the PdMs that Adriano is selling.
I've eaten Gillette and it's not going to make it on the top 100 fig list but it's not terrible.
