Ingredients

1 tablespoon olive oil
2 lbs pork tenderloin, trimmed
coarse salt
ground black pepper
1/4 cup grainy mustard
2 tablespoons Dijon mustard

Preparation

Heat the oil in a large skillet over high heat.
Season the pork with salt and pepper.
Transfer to the skillet and cook, turning, until browned all over, 5 to 10 minutes.
Reduce the heat to medium-low and cover the skillet.
Cook the pork, turning occasionally, until done, 20 to 25 minutes.
Remove the pork from the skillet, cover with aluminum foil and let rest for 10 minutes.
Reserve the pan juices.
To the juices in the skillet, add the mustards, sour cream and any accumulated juices from the resting pork.
Whisk over medium heat until heated through. Do not boil.
Add water if the sauce is too thick.
Slice the pork thinly and serve with the sauce.
