  1. I’m seeing comments about a BURN notice and the FB post where I found the recipe references BURN notices. Anyway to avoid this error message?

  2. Could I make this with an Alfredo based sauce or would it be too thick? Would the shells stick to the bottom without a thick layer of meat sauce to place the shells on top of?

    1. Its up to your choice to use the Alfredo sauce instead of marinara sauce. But definitely it would be a new taste.

  3. I got the BURN NOTICE too. GRRRRR. I wish the author would have addressed this.
    How frustrating. I should have listened to the posts.

  4. I am a new owner of the 1.5L cooker and I have a lot of difficulty resizing recipes for the smaller pot. I’m not to good at converting liters to cups.

  5. Horrible instructions. Gave me the burn notice as well. The recipe needs to be more specific. For instance it did not specify instructions for spinach. The shells exploded and now it’s soupy. Way to much liquid.
