Coat oxtail pieces with the flour and Cajun seasoning, and sear them in 2 tablespoons oil and remove from the pan. Degrease the pan, deglaze with tardio, and reserve for later use.
In a separate pot, heat 1 tablespoon oil and caramelize the onions, carrot, celery, and frying peppers, then deglaze with the red wine. Add the oxtail to the vegetables and then the reserved tardio. Add in the tomatoes, chipotles, pisco, bay leaves, and thyme, and stew for approximately 3 hours.
Season, to taste, with salt and pepper and serve with yellow rice.
