Reduction

Look up a classic recipe for glazed vegetables and it will resemble those demonstrated in my turmeric-glazed carrots video. In this classic approach, root vegetables are covered with water and wine, a knob of butter and a pinch of sugar are added to the pan, and the whole mixture is brought to a simmer. As the liquid simmers and reduces, the starches and sugars contained in the vegetables help to thicken the sauce and emulsify the butter.
