In a skillet brown the Chorizo, breaking it up with a spatula until it's cooked and crumbled. Remove to a paper towel lined plate to drain.Add a tsp of olive oil to the skillet and toss in the onions. Stir and cook for 5-6 minutes or until translucent. Add the garlic and cook until fragrant (30 seconds).Sprinkle in the flour over the onions and garlic, stir and cook until flour starts to brown (about 1 minute).Pour in cooking wine and bring to a boil. Stir in the chopped jalapenos and pickling juice and cook 2 minutes.Gradually add the milk, whisking, and bring to a gentle boil until thickened (about 1 minute). Add the cheeses and reduce the heat to low.Cook, stirring frequently, until the cheese fully melts, (about 3 minutes). Stir in the reserved chorizo. Transfer to a serving dish, or into a mini crock pot, or fondue pot. Serve with chips or soft flour tortillas.Enjoy!
