Ingredients

3 cups ketchup 

1 cup pure maple syrup 

3/4 cup light beer, such as a pale ale 

1/2 cup honey 

1/4 cup cola 

2 teaspoons Blue Ribbon Hot Sauce, or other prepared hot sauce 

1 teaspoon cayenne pepper 

1 serrano chile, seeds removed, if desired, chopped 

Preparation

Combine all ingredients in a heavy-bottomed nonreactive saucepan and place over medium-high heat and bring to a boil. Reduce heat to medium-low and simmer, uncovered, stirring occasionally, until mixture is reduced to 4 cups, about 1 1/2 hours.

Strain sauce through a fine-mesh sieve. Use immediately or let cool completely.
