Brothers I bring you today a good sauce for hot dogs or hamburgers. This recipe is for my secret sauce. Garlic sauce with caramelized onion. 2 medium onions 35 ML olive oil 2 tablespoons of sugar 1 tablespoon of vinegar 6 tablespoons of mayonnaise 1 tablespoon mustard 2 cloves of garlic 1/2 teaspoon salt 1/4 of teaspoon of pepper Cut the onions into julienne strips, and cook them over low heat for an hour, along with the sugar and vinegar, until they are golden brown. In a blender glass we add the other ingredients and mix them with a mixer. Finally, we chop our caramelised onion very finely with a knife, and add it to the mayonnaise. Now all you need is a good hamburger.
