Preheat oven to 300°F
In a large dutch oven, heat a couple tablespoons of oil.
Place the beef in the pot, sprinkle with some rub, and brown.
Remove from pan and continue to cook in batches, until all the beef is browned. (You may have to add the odd drizzle of oil.)
Add the pearl onions, tossing to coat with the remaining oil.
Deglaze the bottom of the pot with about 1 cup of wine.
Let simmer down for a couple minutes, stirring the onions.
Add the beef back into the pot, add the flour, tossing to mix until all traces of white are gone.
Add the potatoes, mushrooms, and parsnips.
In a small mortar place the juniper berries and peppercorns, crushing until broken down.
Add the oregano, thyme, basil, rub, salt and pepper and mix. Sprinkle over the ingredients in the pot.
Stir to mix everything.
Add the dijon mustard, wine, worcestershire sauce, and bay leaves, stirring again to mix.
Place the lid on the dutch oven and cook in oven for 2 hours.
