This is a unique recipe for sure. I was concerned it had no thickening agent, and it was a tad thinner than I would have cared for, HOWEVER, those nooks and crannies of the English muffins soaked up the juices well. I did add a "leetle" garlic and a squirt of dijon to the sauce. I love Welsh rarebit so I knew I would like this. The family enjoyed it as well. Please take care to add the cheese VERY slowly and stir constantly while doing it or you may end up with one oily clump!!
