I decided to reheat my beautiful green avocado beurre blanc and take a picture of it. I really wish I'd had my camera with me last night, or thought about it as soon as I arrived at home.
Alas, Chef Richard was right. There's no reheating the sauce once it's been allowed to chill. It was a mess. A gloppy, green, disgusting mess. It still smelled pretty darn awesome... but really, no one on this Earth would want to eat it! So, for now... I'm afraid I simply can't share a photo.
