Shelagh,
What a battle. My heart goes out to you and your sister. One must give her credit for wanting to stay independent. We never want to give up. I am also glad to hear your sister is gaining some appetite back.
I read the recipe above, and have one suggestion to add. Have her put veggi's thru a blender. potatoes thru a blender..EVERYTHING thru a blender.
Set up your dish with a spoonful of each thing, and you would be amazed at the color on the dish... all mush. Green for asparagus, white for massed potatoes...yellow for eggs.. each one thru the blender separately.
Then when I ate, one mouthful at a time... softened with broth... I could swallow just enough..to enjoy it. So what you don't chew!!! Chewing isn't the best thing in the world.!!!!
My Dad has achalasia, a swallowing disease, for some 5 years now. Mother and I have become expert in the soft mushy diet..because there are times he can't even get a liquid down his esophagus.
I have now adopted many of the tricks we learned to my own situation... They work.
