1/4 cup ( 1/2 stick) unsalted butter, cut into small pieces
Preheat oven to 350 degrees. Season pork with salt and pepper and rub with
mustard.
In a food processor, with the motor running, add garlic and process until
minced. Add bread crumbs, almonds, parsley and herbs and pulse until mixture is
finely chopped. Pat almond mixture over roast, pressing to coat well. Place
roast on a rack in a shallow roasting pan and cook for 1 1/2 to 2 hours, or
until the crust is lightly browned and a meat thermometer inserted into the
center of the roast registers 155 to 160 degrees. Transfer roast to a cutting
board and let stand 10 minutes before slicing.
While the pork is cooking, prepare the sauce. In a saucepan over medium heat,
simmer chicken broth until reduced to 1 cup. Reduce heat and whisk in mustard;
taste. Add additional mustard if desired. Whisk in butter, a few pieces at a
time, until butter is incorporated and the sauce is smooth.
