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.
The healthiest way to go about it is to just have a conversation with your partner if its a concern at all. For some, one’s answer could be a deal breaker, and for others it’s not a problem. Communication is key here.
