I came across this at Epicurious and fell in love, and its been elsewhere. Years of looking for the lemon pasta I remembered as a child, and finally found it. Tweaked it a little to my own taste, replacing parsley with fresh basil and using linguine. If you don't have tender asparagus, the europes best frozen ones are far better than woody fresh ones. Do NOT substitute lighter creams, it just does not work that well.
