Do the Druid's Goodberries rot if you won't eat them immediately ?

I'm wondering if a Druid with a sense for business could set up a small stall in the Druid Grove, near Trader Dammon and Auntie Ethel, to sell Goodberry jam, Goodberry pies, etc. I think Gale is a good cook, so he could prepare those from the Goodberries.

Hoping we'll be able to create great assumptions-free Custom Characters and be given great roleplay options.
