Found this while browseing the Elder scrolls forums today . hadn`t seen it before .
By having ingredients sourced in clear ways and using combinations of food items instead of tiers of ingredients, we will be able to cut the number of ingredients in half while still providing just as many recipes as we have now (if not more). This will require most, if not all, of the existing recipes to be changed to accommodate this new paradigm.
Our current plan is to replace existing recipes and Provisioning items with the ones from the new system, matching quality as much as possible. Any additional unused basic ingredients from the previous incarnation of the system will be changed to “stale” versions of themselves, and we’d like to include some way to offload them that provides value.
