It looks like you have had some good ideas so far....
I can relate, because I am allergic to, ready for this.... pork.
YES...PORK, like in pig.....
I can handle it while prepping, cooking, pulling, etc... but I HAVE to wear gloves, and as soon as I am done, I have to wash up pasted my elbows or anywhere the pork may have touched me. If I get it to my mouth, I am in MAJOR trouble.... almost instant migraine.... for days....
It took me probably around 4 yrs to learn what to look for, and ask when ever we go out shopping or go out to eat. Going out to eat has got to be the worst challenge. Almost every place cooks everything on the same griddles, etc... and the same cooking utensils.
If in doubt, ask, and you will get the answer you need, if in doubt, don't use it. Like it already has been mentioned, use a blend of spices and just leave the sugar out. Allergies are nothing to play with and experiment wondering if something will work.
