I heard someone say this in a video recipe, followed by way more cheese than you should eat at once. It occurred to me that the phrase means ample, not nutritious.
I appreciate this tip, I've had lots of trouble trying to make home made cheese sauce. Even if I felt the flour and milk cooked long enough and I added cheese slowly, I had trouble getting everything to come together. It may be that I still wasnt cooking long enough either because I have a bad habit of scorching the milk, so I would pull it off the burner perhaps too soon. I don't know exact I haven't tried it enough, because I don't like wasting food.
