Special equipment: a silicone baking mat
Preheat the oven to 400 degrees F. Line a baking sheet with a silicone baking mat.
Put the bacon in a small skillet and cook until crisp; drain.
Put the brown sugar, red onions and 4 tablespoons of the butter in a skillet over medium heat. Cook, stirring, until the onions are tender, 6 to 8 minutes, then add the fig jam and 2 tablespoons of the balsamic vinegar. Continue cooking until the onions are caramelized, another 15 minutes. Remove from the stove and set aside.
Put 2 sheets of the filo dough on the prepared baking sheet; brush with melted butter. Add 2 more sheets; brush again with butter. Repeat until you have done this 4 times. Then sprinkle with the goat cheese, spread with the caramelized onions and sprinkle the bacon on top. Repeat with filo as for the bottom layers (4 layers of filo, 2 sheets per layer).
Cut into squares and bake until golden, about 15 minutes.
Meanwhile, pour the remaining 3/4 cup balsamic vinegar and the bourbon into a saucepan over medium-high heat; reduce by half, 8 to 10 minutes. Whisk in the cayenne.
Serve two filo squares to a plate, drizzle with balsamic sauce and enjoy.
