Preheat oven to 325F.
Aggressively season roast with salt and pepper.
Heat Dutch oven over medium-high heat with a drizzle of oil, half a turn of the pan. Once oil is hot, melt 2 tablespoons of butter. Add meat and brown well all over. Remove meat to a platter and reduce heat a bit. Add remaining butter, garlic and shallots. Stir a minute or two, add tomato paste and stir until fragrant. Add in wine and reduce by half. Add consomme, herbs and bay; stir to combine. Add carrots, celery, onions and potatoes, and set roast on top. Cover pan and roast 2 1/2 to 3 hours until very tender. Let stand, covered, while popovers bake.
To serve remove twine, slice, serve with vegetables alongside, meat juices spooned over top.
When meat comes out of oven raise temp to 400F.
Place muffin tin in the oven to heat. Melt butter in a small pot.
In a large bowl whisk up flour, 3 tablespoons melted butter, milk, eggs and salt. Do not over mix. Remove muffin tin from oven and brush cups with 2 tablespoons of butter. Divide batter among the muffin cups and bake 30 minutes until browned and puffed. DO NOT OPEN OVEN DOOR UNTIL POPOVERS ARE DONE OR THEY WILL FALL.
When popovers are just about to come out of the oven, remove twine from the roast and slice. Plate meat with veggies alongside and juices spooned over the top of everything.
Serve popovers immediately with more butter or beef juices for mopping.
