When visiting someone’s home, it is traditional to bring homemade cookies and pies, but make sure you aren’t gifting them food poisoning or an allergic reaction. Take caution in preparation and refrigeration, especially when transporting food in heated cars for long distances. “It is very important to let hosts and other guests know of the ingredients of homemade food gifts and if they were prepared near allergy causing foods,” says Dr. Elliott. “Even if an allergen such as a nut isn’t in the dish, but prepared with the same kitchen tools, there is a potential for an allergic reaction. When visiting others, always have an epi-pen if you have food allergies.”
