Combine the vinegar and sugar in a small skillet and boil over medium-high heat, stirring occasionally with a wood spatula, for 3 to 4 minutes, or until glossy bubbles cover the surface. The syrup is ready when the spatula leaves a path as you run it along the bottom of the skillet. It should be quite thickened and syrupy. Take off the heat and cool before using. Keeps in a sealed jar in refrigerator for a month or more.
