Combine cheeses in a bowl with flour. Add beer to a small pot and bring up to a bubble over medium heat. Reduce the heat to simmer and add cheese in handfuls. Stir constantly, melting the cheese in batches. Stir in a figure-eight pattern with wooden spoon. When the cheese has been incorporated fully, stir in the mustard, hot sauce and Worcestershire sauce. Transfer fondue to warm fondue pot.

In a large skillet, bring 2-inches of water to a boil and blanch the cauliflower for 2 to 3 minutes, drain and arrange around the fondue pot.

In the same pan, bring the cooking water back to a boil and add the mini franks and sliced wursts. Cook, uncovered until all the liquid has evaporated. Add 1 tablespoon butter to the pan to crisp the casings. Pile wursts and dogs near fondue. Complete the dipping selections with dishes of pickles, onions and cubed bread.
