2. Heat a second convection oven to 425°F on high fan. 
3. Add the thawed osso bucco cuts to large stainless steel bowls, along with the remaining 2 oz. of oil blend and season with salt and pepper, as desired. Toss the cuts to coat each side. 
4. Place the cuts on roasting racks fitted inside sheet trays and roast for 25 minutes, flipping the beef after 15 minutes. 
5. Brush half of the basting glaze on the tops of the osso bucco and cook for 5 minutes. At the 20-minute mark, repeat this step on the other side
6. Remove the sheet trays from the oven after 25 minutes and reserve the osso bucco for the braising process.

STEP 3: Making the braise

1. Heat the convection oven to 325°F on high fan.
2. Transfer the roasted tomatoes and onions from Step 1 to a Vitamix blender or equivalent and purée until smooth.
3. Add the red wine vinegar, roasted garlic, honey, brown sugar, cinnamon, oregano, coriander, cumin and salt and purée again until smooth.
4. Transfer the mixture to a large stock pot, followed by the remaining 14 oz. of guajillo paste and 2 gal. of hot water. Whisk until combined and bring to a simmer.
5. Place the osso bucco in a 6″ full hotel pan and pour the chili broth over them. They should be covered by an inch or two of broth. Reserve extra broth for later.
6. Cover the top of the braise with parchment paper cut to fit inside the hotel pan, followed by a sheet of heavy foil over the top rim. Roast in the convection oven for 4 hours.
7. Remove from the oven and allow to cool slightly. 
8. Lift the osso bucco out using tongs and pull the meat, placing it into a stainless steel bowl. Discard the bones, but ensure all the marrow remains with the braising liquid.
