Most brands of light ranch dressing will be thin enough to run through the fountain. If regular ranch is being used or if the light ranch is too thick, gradually add milk until fondue reaches appropriate consistency.
Yield: Enough to run through the largest home fountains. Multiply quantities by 4 for large commercial fountains.
Note: Select fountains hold 5-7 cups of fondue; Classic, Elite, and Signature fountains hold 7-9 cups.
