Troja

HI i Enjoy the mod very much as the cook of my friends private server and i have some questions that are not very easy to find out. How do i use lard after it solidifies? every recipe is not taking the Hardend lard and i for the life of me can`t find a method to make it a liquid again. the Second thing is with the toppings how do they work? i try to do 1l of broth into a stew and nothing happens is just wont work.
