Pork tenderloin was on special and I picked one up for less than $4! I cut it into 1.5 inch pieces, stood them on end and flattened them. I shook them in a bag with some salt and set them on the counter. Potatoes were boiling away and I was going to do the carrots and peas together in the microwave. I prepped them as well as slicing the mushrooms and dicing a shallot.
The sauce started with shallots caramelizing. Take them out of the pan and add the mushrooms. Get a good sear and take them from the pan. Next two teaspoons of flour and enough oil to make a paste. Cook the flour taste off for a minute then add an ounce of chicken stock and two ounces of white wine. Add some salt, pepper, fresh garlic and fresh parsley amd a pinch of mustard powder.
I didn't taste the sauce before serving it which was a mistake. It looked delicious but tasted anemic. I'm not sure where I went wrong not developing enough flavor. Maybe I should have made the sauce in the pork pan while the meat was resting or maybe the mustard masked flavor instead of adding to it.
