Chori Burger with Caramelized Onions Recipe

To make chorizo burgers, spread butter on the inside of each bun. Toast until warm. 

Make the garlic mayonnaise: mix together mayonnaise, garlic, and lemon juice. Season to taste with salt and pepper.

Make the caramelized onions: heat 1 tablespoon each olive oil and butter in a frying pan over medium-low heat. Add white onion and cook until soft and golden, about 6 to 8 minutes. Add sugar and continue cooking for 1 to 2 minutes. Add chicken stock, season with salt, and cook for 1 more minute.
