To make the candied jalapeños, Add the vinegar, sugar and garlic powder to a small saucepan over medium heat and whisk until the sugar dissolves. Allow the mixture to boil for 2 to 3 minutes, then add in the peppers and stir with a wooden spoon, making sure all of the slices are submerged. Cook for 3 to 4 minutes. Remove the peppers with a slotted spoon and place them in a jar or a bowl. Continue to cook the liquid for another 5 minutes until it has reduced by half, then pour it over the jalapeños. Allow the peppers to cool completely – you can do this a day ahead of time too.
To make the caramelized pineapple, heat a large skillet over medium heat and add butter. Add the pineapple rings and cook until they are golden and caramelized, about 5 minutes per side.
To make the burgers, mix the ground beef with the salt, pepper and minced garlic until combined. Form the burgers into 4 equal patties. You can grill the burgers but if I’m photographing, it’s easier for me to cook them in a skillet. I usually add a tablespoon of butter and cook on medium high heat until the burgers reach medium-well doneness. In the last minute, I add the cheese on top and cover the burgers, allowing it to melt.
To make the sweet chili mayo, whisk together the mayo and chili sauce in a bowl until combined.
To assemble the burgers, add the burgers to the bun and top it with the bacon, the pineapple and the candied jalapeños. Spread the sweet chili mayo on top of the bun and and serve immediately!
