Mostly this famous Bavarian cheese dip is made with beer. There is gluten free beer, but considering how expensiv it is, I wouldn't waste it for cheese dips... When I visited my friends near Munich lately, they told me that they actually make obatzda without beer. So this is it :-) If you want to keep the dip for some days, omit the shallot and serve with thinly sliced onion instead. Cooking time is refrigeration time.
