Here's another. This ain't easy, but it will knock per socks off! The sherry is essential to the flavor, IMHO.
PORK & MUSTARD STROGANOFF
This take on traditional beef stroganoff is a little lighter, but the flavor is
boosted with addition of brown mustard. Brands of mustard will vary in
intensity, so taste as it is whisked into the sauce.
1 pound pork tenderloin, silverskin removed
kosher salt
freshly ground pepper to taste
3 tablespoons olive oil, or as needed
6 tablespoons dry sherry, Amontillado preferred
1½ tablespoons soy sauce
1 large onion chopped moderately fine
2 teaspoons minced garlic
½ ounce dried porcini rehydrated in hot water to cover
3 tablespoons unsalted butter
¾ pound cremini mushrooms, cleaned and sliced
1½ cups beef broth or stock
1½ cups chicken broth or stock
1 bay leaf
1½ teaspoons minced thyme
4 parsley stems
¼ cup brown/whole grain Dijon mustard
1 teaspoon sherry vinegar
1 teaspoon Worcestershire sauce
½ cup sour cream
2 tablespoons softened butter
1½ tablespoons all-purpose flour
12 ounces medium-size egg noodles, cooked
finely chopped parsley (optional garnish)
1. Season tenderloin to taste with salt and pepper. Preheat a Dutch oven
to medium-high; add just enough oil to coat skillet bottom, about 1
tablespoon. When oil shimmers and is just short of smoking, add
tenderloin. Brown on all sides, waiting to turn meat until it releases
from the pan when shaken.
2. Set pork aside to cool, about 15-20 minutes (keep Dutch oven with
browned bits - the fond). Cut tenderloin in half lengthwise, then cut
each half crosswise into thin slices, about c- to d-inch thick. Combine
2 tablespoons of the sherry and 1 tablespoon of the soy sauce in a
bowl. Add the meat and turn to coat thoroughly. Refrigerate until ready
to cook.
3. In the same Dutch oven over medium heat, add 2 tablespoons oil and
chopped onions. Cook until onions turn golden brown, about 6-8
minutes. Add the garlic and cook a minute more until garlic becomes
fragrant. Transfer onions and garlic to a bowl and reserve.
4. Meanwhile, swish porcini in the water to remove any grit; remove
porcinis and chop moderately fine. Strain soaking water through a
coffee filter; reserve porcini water.
5. In the same pan, add the butter and sliced cremini mushrooms.
Season to taste and cook, stirring occasionally, until mushrooms have
released their moisture and are almost half their original size, about
4-5 minutes. Deglaze with the rest of the sherry and cook briefly until
liquid is reduced by about half.
6. Add porcini, reserved onions and garlic, reserved porcini water, beef
and chicken broths, bay leaf, thyme and parsley stems. Simmer
uncovered, about 20-25 minutes, or until liquid is reduced by one-third.
Remove and discard bay leaf and parsley stems. The recipe can be
prepared ahead to this point; reheat before proceeding.
7. Whisk in mustard, vinegar, Worcestershire sauce, the remaining soy
sauce and sour cream. Simmer for a few minutes to meld flavors.
8. Meanwhile, combine the butter and flour in a small bowl. Whisk
butter-flour mixture into the simmering liquid. Taste and adjust
seasoning.
9. Add pork and cook until cooked through, about 5 minutes, stirring
occasionally.
10. Taste and adjust seasoning once more before serving immediately
over hot, buttered egg noodles. Garnish with parsley if desired.
