This is a great dish. I was sceptical of the recipe making enough for two, but it really does. I do not like tarragon, used basil instead; used bow tie instead of penne. Also, added some fresh sugar snap peas to it. Not good with sauces, I was a little nervous, but the sauce is easy and cooks up great, no lumping or clumping. Loved the lemony flavor. This is a keeper!
