Did you think they didn't know how to have a party up there?
Look, what they don't have (in older times of course) is what for flour and grapes for wine. Hard to hold communion. The heresies began immediately!
They may not have grown those particular crops, but that didn't keep our Lord and Savior, Christ Jesus from still providing the Body of his human nature to be broken and for all of us to commune with, as well as the blood of the New Covenant, still available to any with faith alone in Him alone to fulfill the communion.
