Check the brown bits
Remove the cooked mushrooms. Keep the golden-to-brown residue, called fond, but discard excess loose oil. If the residue is black or smells burnt, wash the pan and start with fresh stock; bitter burnt bits cannot be rescued.
Keep brown fond, but avoid burnt black residue. Deglaze gently
Lower the heat and let a smoking pan cool first. Carefully add the stock to the warm pan, keeping your face and hands clear of rising steam. Scrape gently with a wooden spoon to dissolve the brown bits.
Loosen the fond with stock and a wooden spoon. Reduce with control
Simmer until the liquid is reduced by roughly half, watching the depth rather than the clock. Stir in the mustard. Taste a cooled spoonful before adding salt: reducing concentrates the seasoning.
Simmer to concentrate the sauce. Finish off the heat
Take the pan off the burner and swirl or whisk in small pieces of cold butter. Add a few drops of lemon if the sauce needs brightness. Spoon over the mushrooms and serve promptly; do not boil after the butter is added.
Finish off the heat for a glossy sauce.
SMALL FIXES, BETTER RESULTS
If it doesn’t go to plan
The sauce looks oily?
Take it off the heat and whisk in a teaspoon of cool water. Add more only a little at a time.
Too thick or salty?
Loosen with a small splash of water or unsalted stock. Taste again before reducing further.
