(i): item
(f): fluid

1. Caramel:
   With existing blocks:
   Cream(f) + sugar(i) in brew kettle--->caramel(f)
   Add new block:
   Maybe a pot kind of thing that works like the cheese vat with multiple fluid and item input.
   Water(f) + sugar(i)--->cooked sugar solution(f)
   cooked sugar solution(f) + cream(i)--->caramel(f)
   Caramel(f) needs to be molded into caramel bar(i). It will act like food, a fondue base ingredient, and chocolate stuffing(see below)
2. Raisins:
   New block: drying rack.
   Put grapes on drying rack and it will turn into raisins. The color depends on that of the grapes used.
   Raisins will also act like food and chocolate stuffing.
3. Chocolate stuffing:
   It takes place in the moulding process. You'll need to put a layer of chocolate paste into the mold, top it with stuffing ingredient, and cover it up with another layer of chocolate paste.
   Stuffed chocolate won't be able to be melted in fondue pots.

Kinda like it :)
