I am wondering about your foaming butter recipe. You indicated using one pound of foaming butter but when I ordered the ingredient it had a warning "DO NOT PROCESS WITH LESS THAN 5 LBS". Other websites had different amounts. Is it ok to make this recipe with 1 lb if they have that warning? What is the cause for this warning? I do not want to make this recipe with 5 lbs of foaming butter. Please help.
