My grandpa, drawing ever closer to 100 years old, is only able to eat pureed foods, those with a pudding-like consistency. He yearns for whitefish, white flakes, straight from the fish, the kind you get from Zabar's.
While visiting today, his caregiver told me that he keeps asking for whitefish. I had left some in his refrigerator and he had spied it. She said, "Let's wait for your granddaughter to come and she will prepare it." He replied, "There is nothing to prepare. Just peel off the skin and give me a fork." When we tell him that he can only eat pureed foods he says that we are all full of baloney.
I took some of the fish and blended it, along with sour cream and a bit of milk. It retained its whitefishy aroma and when he was fed, she couldn't get it in his mouth fast enough. He even pushed her to give him more.
Even then, he kept requesting "real" whitefish and it was sad not to be able to give it to him but better to deny him chunks of whitefish than to watch him have a coughing attack. Just have to keep coming up with creative ways to give him the foods he loves.
