How can you achieve good flavor with only 30 mins of everything cooking? Plus what about the layer building with wine, sherry, and broth? Can't add them all at the same time, the balance will be off without layered additions. Mine takes 4-6 hours total, and I usually make ahead, and finish the following day, letting the flavors meld together.You can go from a bag of onions to bubbling cheese on top of dark brown onion-y goodness in under 2 hours.
