The flavor of this pasta dish was really good. I didn't add the chiles because I planned to share it with my 2 year old, but I did add chile flakes to my portion. I liked it, and might make it again if I have feta and fresh corn on hand.
This dish was just ok. It tasted better than it looked (I really dislike "vampire" food- food whose color and vibrancy seems to have been sucked out by cooking.) The mushrooms, corn and feta were all the same color. I added some pepper strips and some peas for visual interest. Perhaps yellow corn would also be more interesting.I would also recommend sauteeing the mushrooms for a bit more crispness, rather than braising them in the butter. Adding the pasta cooking liquid didn't add much; we barely added 3/4 cup. I would stick with just the cooking liquid from the mushroom mixture, and maybe a bit of olive oil. Definitely use the chiles- they added a lot of flavor as well as heat. It really did taste good, it just looked so unappetizing.
