We just polished off a couple of bowls of this treasure inspired by the insane Alton Brown and are laying here all slothful and stuff. Ok, it wasn’t exactly “inspired” by him...it's his recipe with a couple of molestations by me. I've omitted his inclusion of apple cider as I didn't like what it did to the flavor (way too sweet) and increased the broths. The combination of gruyere and Emmenthaler cheeses works far better, in my estimation, than the commonly seen solo gruyere. And no optional splash of cognac for us -- though if you were to add it, I’m relatively sure you’d be safe from my wrath. But I think the secret here lies in the way the onions are cooked...until they submit and obey.
