My source for this recipe is "From The Recipe Files of the C.I.A. (Culinary Institute of America) Cookbook". I rarely enter part of a recipe, but this 1 was for an asparagus sauce to compliment cheese omelets. The omelet part of the recipe was routine & the asparagus sauce so appealing that I opted to enter the sauce & leave you to your own omelet choices. I entered the sauce recipe as written, but frankly feel I need to comment. Few of us who love asparagus would dispute the use of fresh asparagus is much-preferred, if available & a part of an entree or side-dish. Fresh asparagus is hard to find here in Iceland & very expensive. In a pureed sauce, I think the canned variety would be just as good, it certainly simplifies the prep & it substantially reduces cooking time. It is a no-brainer for me, but it may be another choice for you.
