My mother just brought me a whole cheesecake from a local kosher bakery because I wouldn't let my son have a slice of cheesecake they brought home from a non-kosher diner. She meant well, but I JUST decided to get all the gluten out of my kitchen and then this cheesecake appears...
I wrapped that up well and put it in my freezer for now, and plan to serve it on paper plates when we're having guests (and when I'm planning to give my daughter a gluten challenge anyway.) So I'm not really asking what do to THIS time, but I'd like to know how I should handle this if it comes up again, and how everybody else deals with this issue.
