I thought the same, but you can replace the cauliflower with broccoli if cauli isn't your thing. The heavy gets too heavy. Give the beer cheese soup a shot on its own first (if you want, leave out the veggies and sop it with sourdough--super delicious).
It's one of those things that many people had to approach me with first, each with the rather suspicious "just trust me..."
But, my friend, give it a shot I did, and all I can say is, uhh, just trust me.
One thing I've noticed, after making a few batches, is that you should use a medium to sharp cheddar. The mild stuff gets lost in the flavor mix.
And the sourdough sop, can't reccomend that enough.
