Would create the create food and drink spell create soda pop if the caster actually drank such a item once or do you need to make it via alchemy?
Create Food and Water
The food that this spell creates is simple fare of your choice—highly nourishing, if rather bland. Food so created decays and becomes inedible within 24 hours, although it can be kept fresh for another 24 hours by casting a purify food and drink spell on it. The water created by this spell is just like clean rain water, and it doesn’t go bad as the food does.
So no fizzy drinks for the cleric.
