Trim the oxtails of some of their excess fat. Brown all sides in a little oil.
Put oxtails in large pot (or crock pot).
Add stock, bouillon, crushed red papper, sugar, ginger and soy sauce. Simmer for about 1 hour (for crockpot - cook about 2 hours on high setting).
Add corn, carrots, onions, plaintains, red pepper, green pepper, jalapeno, habenero and red wine. A nice cabernet bottle works well and there will be enough for you to drink three glasses as you cook if you're feeling a bit self-destructive.
Simmer for another couple of hours or until oxtail is fall-off-the-bone tender. If using slow cooker, this will take another 4-5 hours depending on how large your oxtails are.
When all tender, remove the oxtails from the stew and let cool. Pull the meat from the bone and set aside.
In a separate pan, the butter on low and slowly stir in the flour until you have a roux. Add only about half of this to the stew and see how well it thickens after you've cooked it about 5-10 more minutes. You usually won't need anymore roux.
Stir in the reserved oxtail meat.
Let it all cool. Cover and put in refrigerator for at least 8 hours. Oxtail is very fatty so there will be a significant layer of fat after it has been refrigerated. Spoon off the fat.
Reheat and season with salt, pepper, red pepper, and/or garlic to taste. Garnish with fresh parley and serve hot.
