Is the only allergen concern peanut and tree nut? If so I'd skip the indie bakers obsessed with gluten free as a lifestyle health promotion. Coming from someone who has kids one PA and the other ana to wheat, barley, usually the two are mutually exclusive. The only ones I know of that really get it as in an honest to goodness bakery is Franz and that's because I talked to them leaving no stone unturned and they answered in a clear way signifying they "got" it. Like we do.

There's also a Rudi's. I haven't used it so I don't have any info.

Are you talking about Udi's?  I've never heard of the brand Rudi's.  Off to Google.  But in the meantime, here's the Udi's website.. they're also gluten free.

Has anyone had their products before? It seems the non-gluten are not nut safe but the gluten-free ones also are nut-free. Was going to give them a try and seeing if anyone else has already?  Dealing with PA/TNA
