Purity of potables

Have the purity of potables play some rule in the food we make. But instead of affecting amount of biles make them affect food category restoration. At 100% they would restore 2x more (or 2x more often) food category.
To make it more consistent have each potable restore some food category, even if only by a small amount (for example 50% chance to restore by 5%). So carrots, parsley, raddishes etc.
For example carrots would restore potatoes, raddishes would restore pumpkins, parsley would restore berries, oakworth would restore shellfish and so on.
