Asparagus is another shun ingredient I picked up at the grocery store. Asparagus season begins around mid-April and lasts about two months. So strictly speaking, it's a little far ahead. But since Wegmans had beautiful asparagus, I reached for a bundle.
Though it is cream based, this pasta is very light and refreshing. When you make lemon zest, try to grate only the outermost, yellow part of the lemon skin. The white part of the lemon, the lemon pith, is very bitter, and it will give your dish an undesirable taste. Any grater/zester should work fine, but I like Microplane Grater/Zester. It works very well for this job.
The chicken can be substituted with different proteins such as shrimp, squid, salmon and prosciutto. If you are vegetarian, omit the chicken and use vegetable stock in stead of chicken stock. That works just fine.
