Why It Works

Reduction

Sauce Making

Seasoning before reducing — the most expensive mistake in sauce-making. You salt at one cup, reduce to half a cup, and the sauce is twice as salty as you intended. Reducing too aggressively — a hard boil can take a sauce past the sweet spot in 30 seconds. You can always reduce more; you cannot un-reduce. Over-shooting — if you reduce too far, the sugars and proteins begin to caramelise on the bottom of the pan, adding burnt bitterness. Add unseasoned stock (not water) to rescue an over-reduced sauce. Reducing wine without cooking off the alcohol first — raw alcohol has a harsh, volatile taste that concentrates if you just simmer. Bring wine to a vigorous boil for 60–90 seconds first to drive off the ethanol, then reduce the heat and simmer to concentrate the flavour. Not tasting throughout — a reduction crosses multiple flavour stages. If you're not tasting every minute during the final stages, you'll miss the peak.
