What is “fond” and do I really need it?
Fond is the browned bits stuck to the bottom of the pan after searing meat. It is basically concentrated flavor. You can still make this sauce without much fond, but it will be lighter and less savory. If your pan is very clean, add a pinch more salt and a little extra acid for pop.
Can I make pan sauce without wine?
Absolutely. Use more broth, plus lemon juice or vinegar for brightness. Wine is nice, not required.
Why did my sauce taste bitter?
Usually one of these culprits: the fond got too dark (burnt), the garlic scorched, or the wine reduced too far and turned harsh. Over-reduction can also concentrate bitter notes that were already there. Next time, lower the heat and deglaze sooner. To fix bitterness now, whisk in a bit more broth and finish with butter. A tiny pinch of sugar can also help in a pinch.
Why did my sauce break or look greasy?
That typically happens when the heat is too high after adding butter. Take the pan off the burner and whisk like you mean it. Add a teaspoon of cool water or broth to help it emulsify, then whisk in cold butter a little at a time.
How do I thicken pan sauce?
Most of the time, you just reduce it by simmering. If you need a quicker, thicker result, whisk 1 teaspoon cornstarch with 1 tablespoon cold water and drizzle it in while simmering for 30 to 60 seconds. Keep it subtle or it starts tasting like cafeteria gravy.
What acid is best: lemon or vinegar?
Lemon is bright and clean, great for chicken and fish. Vinegar is punchier, great with pork and richer meats. Use what fits the mood, and start small. You can always add more.
