What a fun coincidence. They live near Malmo in the countryside. I’m sure if you’re with family with a kitchen you won’t have any issues. Have you looked at recipes and diets for people that have their jaws wired for recovery after a surgery? My husband had jaw surgery relative to a dental issue and had his jaw wired. So he was on a liquid diet for some time including winter holidays. You might get some good ideas on how these people fulfill their diets. Best wishes
