I have a family member who has a nut allergy so I’m use to baking for him and know what products to stay clear of (I’m an avid label reader).
Regarding orders, my cake agreements contain an allergy indemnification clause but concerning these 2 particular cake orders, as soon as they advised me of the nut allergy, I told them there was a very good possibility that chocolate may be off the table for their orders, but I would make the best effort to try and accommodate them. On that note – I’m happy to say, I found 2 chocolate brands that are in fact nut free . . .
