My sodium citrate cheese sauce keeps thickening like crazy after it's off the heat Not sure what to do. Recipe is
&gt;1 cup liquid + seasonings 

&gt;4tsp sodium citrate 

&gt;half stick butter cold

&gt;add handfuls of cheese and whisk till smooth cheese sauce 

Normalls 4-5 handfuls of cheese

Maybe I need to use less cheese? Or take it off the heat when it's too runny? Or more liquid idk. New to  sodium citrate
