How many cups of hot chocolate powder do you put in a forty cup percolator?

For a 40-cup percolator, you typically use about 1 to 1.5 cups of Hot Chocolate powder, depending on your desired richness. Start with 1 cup for a milder flavor, and adjust to 1.5 cups if you prefer it sweeter and more chocolatey. Always check the specific instructions on your hot chocolate powder packaging, as different brands may vary.
