Wow, I assume homemade recipes could avoid nut allergies, right? As for forms and special stuff, there is a place in Corridor Marketplace in Laurel on 198 just off 295. Maybe they can help with the allergy thing too. (right beside a Kohl's)
Maybe go to the nearest large bookstore and see if they have any allergy cookbooks. The other lady is right, allergies are pretty prominent theses days, you would think companies would start catering to it.
Boy, I feel so lucky. My kid's not allergic to anything. Hopefully he'll outgrow the nut allergy too. Wouldn't that be cool. Good luck!
