Experimental
Most cheese won't melt in liquid by itself. The oil and proteins will separate. Add sodium citrate, an emulsifying salt, to get cheese to melt in liquid.
Sodium citrate should be 2%-4% of liquid (not cheese, not total). Liquid from 35%-85% of cheese will be thick like for dips and queso. Liquid from 85%-120% will be thinner, for fondues and mac-and-cheese.
