2 1/2 cups shredded Cheddar cheese
1/3 lb Gruyere cheese (shredded)
1 rounded Tbsp all-purpose flour
1 cup German lager beer (Bud Light will work if you have no German beer)
2 Tbsp spicy brown mustard
A few drops of hot sauce
A few drops of Worcestershire sauce
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 a 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.
