Peel and dice the Yuca and Onion. Mince the garlic. Chop the cilantro. Store in the fridge or place all in the slow cooker – but save some of the cilantro for garnish.
Cut the short ribs into 2-3 inch pieces. In a bowl or baggie, mix the flour with a pinch of salt and pepper. Coat the outside of the short rib pieces on all sides. Shake off excess and add to a preheated pan over medium-high heat with Extra Virgin Olive Oil. Sear on all sides.
Once seared, turn off the heat and add the wine. Scrape up all of the browned beef bits from the bottom of the pan. Transfer the meat and wine to the slow cooker. Note: if not using red wine in this recipe, replace with 1 cup of broth.
Add all of the ingredients to the slow cooker: yuca root, onion, garlic, cilantro, broth, tomato paste, diced tomatoes, red wine, oregano, bay leaf, pinch of salt and pepper.
Stir to combine ingredients, then turn slow cooker on high for 6 hours (or longer based on your schedule).
At 6 hours, test for seasoning and add salt and pepper as needed.
