Fry bacon in a large saute or cast iron skillet (10-12 inch), remove bacon. Put sliced onions in pan with bacon fat on medium heat, add salt,cook, stirring occasionally, allowing onions to caramelize. This is a slow andimportant step. You do not want to burn the onions. (15-20 mins)
When onions start to get jammy, add the water to loosen. Addthe garlic. Keep cooking down until garlic browns slightly and becomesfragrant, add the sugar, cook another minute. Add the Chipotle Ketchup, stir inwell and cook another minute to two. Remove from pan and store in a jar. It’sgood for a few weeks in the fridge and can be used on burgers, hot dogs, and ofcourse, in the best baked beans ever.
