Lobster Thermidor, Steak Diane, and Beef Wellington are not common anymore, because people don’t order it. Its 2010, not 1975.
And, who uses canned/jarred hollandaise? That crap tastes like bland cheese whiz. No respectable restaurant serves it. Only $4.99 breakfast joints use that crap.
As for making hollandaise, many people think they know how to make it, but they don’t. Until you can achieve a stable 3 oz : 1 yolk butter to egg ratio or better, your technique needs work. And if it comes out the color of yellow mustard, you cooked it too fast.
