For the Lime Crema - Put all of the ingredients in a bowl and whisk together. Transfer to a container, cover and chill for at least 30 minutes. Ingredients for Lime Crema include: Sour cream, heavy whipping cream, lime juice, lime zest, granulated garlic, kosher salt
To make the barbacoa - In a blender, combine the vinegar, tomato paste, garlic, cumin, oregano, cloves, pepper, salt, lime juice, chipotle peppers, adobo sauce, sugar and stock. Blend to combine. To at least a 6qrt pressure cooker, add the chicken, bay leaves and the liquid from the blender. Lock the lid, set the timer for 10 minutes on high. When the timer is done, do a quick release on the pressure.
Remove the lid and shut off the pressure cooker. Using tongs, take out the chicken pieces placing them either into the bowl of a stand mixer fitted with the paddle attachment or on a plate. If using the mixer, turn it on and mix just until the chicken is shredded (leave some chunks). If doing it by hand, use 2 forks and shred the chicken. Remember you want some bigger pieces.
With the liquid still in the pressure cooker, remove the bay leaves (discarding them) and place the shredded chicken back into the liquid. Add in the 2 tbsp. of cilantro, stir and let it rest in the liquid for a few minutes. Strain the chicken reserving the liquid for rice or another use.
In a large, ungreased pan over medium heat add Mission® Super Soft Flour Tortillas to the pan and cook for 15-30 seconds or until warmed through. Repeat until all are warmed through.
To the bottom of a warmed tortilla, add some barbacoa chicken, Cotija, lime crema, radish slices, cilantro and chopped tomatoes.
