Hi,
I wanted to report this issue :
Food Plus' caramel and MFR's sugar charcoal have both the same recipe : sugar in a oven.
Caramel allows you to create candies, and with those candies, you can create powerful stuff, tools and armor.
I don't remember what is the use for sugar charcoal, but I think that if it exists, then it must be useful.
I found a fix for this issue : Food Plus adds Candy Flowers, which can be found in grassy areas.
So what you have to do is to add a SmeltingRecipe with Candy Flower in input and caramel in output.
I hope I helped,
Paul
