I find Cheese Whiz more salty than Velveeta. That said, I'll use a combination of Velveeta and sharp, white cheddar. Mix in a touch of yellow mustard, or mustard powder to give it a bit of bite.
First, heat a little milk (about a quarter cup), and start adding the cheese. You can change the flavor profile by adding herbs such as oregano, garlic, basil, etc. A little liquid smoke changes the flavor as well, depending on what you are dipping into the fondue.
Another option is to add browned ground beef, pepperoni bits, bacon bits, or sausage bits to your fondue. Be creative. Try all kinds of things.
Make a hot, white chocolate sauce to dip strawberries in, or a flavorful marinara for breadstics. You can make anything into a fondue, almost.
I'm not sure where your question about rude people came from. The responses I saw were quite helpful. Maybe the rude post was removed. The moderators here are very good at that.
In any case, I hope you enjoy DiscussCooking as much as the rest of us do. And I hope your fondues come out just as you like them.
