I'm grateful to find others sharing their experience of this. Three years ago I started getting fruit from trees I'd planted over 10 years earlier. The first year there were only enough fruits to eat them raw as they ripened. Last year there were so many, I tried pureeing and freezing, and also cooking. My partner and I were terribly nauseated, and I thought maybe I'd failed to cut out a bad spot or something. This year I have hundreds of fruits. I carefully washed, peeled, pureed, and baked a delightful dessert bread to share with my friends. Out of five of us, only one person was not terribly nauseated by the bread.
Apparently I can enjoy pawpaws ripe, scooping the custard right out with a spoon and directly into my mouth, and in ice cream. I'm so sad about not being able to cook them but I'm giving bags of pawpaws to my buddies and telling them they probably shouldn't cook 'em, either.
