This is kidney and gall bladder and not testicles as we thought before we looked it up. Because kidneys and gall bladder are so much better than testicles.
And for good sport, I'll just tell you what else is fair play in the world of French gastronomy: andouillette (bowells), tête de veau (calf's head), escargot (snails), cochonaille (anything related to a pig, including ears, stomach, etc.).
I am totally getting my fill of adventure. Really Really, it's enough.
