The “W+C Burger” included Cheddar cheese, smoked mayo, bacon, and a secret ingredient, bourbon onions. The meat was delicious, rich in flavor, topped with several strips of bacon, each mildly salty, to complement the beef and the “Bourbon Onions.” The melted Cheddar cheese was creamy and added a touch of nuttiness, and the mayo, which was smoked, a smidgen of smokiness plus more creamy delight. The toasted brioche bun was the perfect choice for this combination. The killer ingredient, and this may be the best topping I tasted, was the Bourbon onions. These were also some of the most delicious caramelized onions I have ever tasted. They were sweet, buttery and the slight crispiness from grilling was a bonus.
