I fear and loathe making hollandaise and bearnaise is just the same thing with more work involved. Not that I don't know how but its difficult to make just a single serving and it doesn't keep well. I'm thinkin' DEFCON 2 brushed on and then lime zest creme fresca drizzle. Then again I haven't cracked a beer yet so who knows.
Seriously dude - if I can figure out how to use charcoal in my electric outdoor grill and bake a pizza, you can come up with something better than that, no sweat. Heck, you're even in Texas - no power needed 'cept TEXAN power!
