I don’t usually cook from recipes, but here goes:
Make stock
- Put a strip of bacon and some olive oil in a Dutch oven, and cook on stovetop.
 - Cut rabbit into sections and coat liberally in salt and pepper, and brown both sides in the Dutch oven.
 - Add carrots, celery, and onion to the pot and cook until softened.
 - Add garlic
 - Deglaze with red wine
 - Add tomatoes, rosemary, thyme, and chicken stock
 
Cook rabbit
In oven on 500 Fahrenheit (260 Centigrade) for two hours
Make sauce
- Strain solids from stock. Also remove rabbit
 - Add more chicken stock, heavy cream, and dry English mustard, and cook on stovetop on medium-high heat (15-30 minutes)
 - Pick rabbit meat from bones, add rabbit meat back into sauce, and simmer over low heat (15-30 minutes)
 
I also added marscapone and cornmeal dumplings.
