Mushroom Jus - 2-Qt. Pressure Cooker - cooking recipe

Ingredients

3 1/2 tablespoons clarified unsalted butter (or other neutral oil, see recipe description, 55 mL or 50 g)
4 cups cremini mushrooms (300g) or 4 cups portabella mushrooms, thinly sliced (300g)
2 tablespoons dry porcini mushrooms, crumbled (15 g, optional for an earthier flavor) or 3/4 cup smoked bacon, thinly sliced (75 g, optional for a more savory flavor)
3/4 cup shallot, thinly sliced (80 g)
1 2/3 cups water (400 mL or 400 g)
1/3 cup fino sherry wine (80 mL or 80 g)
1/3 cup dry white port (80 mL or 80 g) or 1/3 cup Chardonnay wine (80 mL or 80 g)
2 tablespoons white miso (28 g)
3/4 teaspoon soy sauce (3 mL or 4 g)
salt, to taste
sherry wine vinegar, to taste

Preparation

Over high heat, melt clarified butter or neutral oil in pressure cooker. Saute mushrooms and shallots (and optional porcini mushrooms or bacon) until the mushrooms and shallots turn golden, about 12 minutes.
Add the water, sherry, and port or Chardonnay. Combine with mushroom mixture.
Secure lid, and pressure-cook at 1 bar (low pressure) for 25 minutes. (Start timing as soon as full pressure has been reached. (If your stovetop runs hot and you have difficulty maintaining only 1 bar of pressure, either double stack burner grates or use a heat diffuser.).
Remove from heat. Let cooker depressurize naturally.
Strain the stock through a fine sieve. Discard the solids.
Measure 2 cups of the mushroom stock (500 mL or 500 g).
Into the measured 2 cups stock, blend white miso and soy sauce. Allow to infuse for 4 minutes.
Strain.
Season the jus with salt to taste and/or sherry vinegar to taste.
Serve the jus warm.
