I want to send some regular chocolate chip cookies via mail. It would take approx 3 days (2 min, 4 max I'd say) since sent, to get there. Temperatures can get hot now but it's not urgent so I can wait until the weather has a daily max of 26º C, which is nicer than 40. Dry weather sending, currently unknown if dry or humid weather receiver.
I have read about the same topic regarding cookies and cheese, and some external sites like Land o Lake, how to ship cookies and from better home and gardens as well.
I have the feeling I am not understanding how moisture works or affects cookies depending on the material used. I thought aluminium foil was used mainly for temperature "insulation", and plastic film wrap to keep moisture/not drying out. Depending on the site of the links above, some mention aluminium foil, others plastic wrap and also "either of them".
I would say that as long as cookies are not VERY dry, they´ll be fine texturewise. The oils inside the cookie and chocolate chips might also help. Before reading the articles, I would have wrapped them in plastic wrap, and wrapped that in aluminium foil.
Does wrapping cookies in aluminium foil only, differ on conservation than on plastic wrap only? Is using both or only 1 a good idea depending on the weather conditions?
(I did not add the preservation tag as it is not for long-term, would it be food safety?).
