Unagi Glaze

This is a simple recipe that Chef Gabriel Claycamp gave us during class at West Seattle's wonderful cooking school, Culinary Communion. Posted with permission.

• Ready In: 15 mins
• Yields: 1 batch

Ingredients

• 14  ounces  commercial  teriyaki sauce (bottled sauce, not thick glaze, Kikkoman's is okay in a pinch, about 14-16 oz)
• 1⁄2 cup brown sugar
• 1⁄4 cup  rice wine vinegar
• 1  teaspoon  peeled and chopped gingerroot, to taste

Directions

1. In a pan, combine all ingredients over medium low heat.
2. Reduce by about three-quarters, beginning to taste it about halfway through the reduction. It should be full-flavored and sweet and tangy.
3. Strain mixture and use.
4. To use: brush on the unagi, broiling the unagi in oven or grilling it.
5. You can also let the mixture cool, and store the glaze in a clean bottle in the fridge.
6. Here are the actual instructions Chef gave me, in his wording: "Unagi glaze is very simple. Just reduce bottled terriyaki sauce with a 1/2 cup of brown sugar and 1/4 cup of rice wine vinegar. Add some chopped up ginger. Reduce this by about three quarters. Start tasting around halfway. It should be full-flavored and sweet and tangy. Strain and brush on the Unagi under the broiler, or on the grill".
