How else do you cook your Hollondaise sauce for the sparrow grass?

you cheat!
-melt the butter in a micro wave, and make the hollondaise in a blender.. sure it gets whipped up and is lighter and airier than the real stuff... but that's okay. it never curdles, and its fast!
(put egg, lemon juice and a little dijon mustard in bottom of blender,(and a dash of salt and pepper) Melt butter,
Start blender and immediately start pouring melted butter in a thin but steady stream-- turn blender off as soon as all butter has been added. serve asap.)
