Nutty sesame oil balances the sparkle of fresh ginger. A combo of black and white sesame seeds makes for striking presentation, but if you can't find the black ones, just use 2 teaspoons of white seeds.
Sesame seeds have a mildly sweet, nutty flavor that is enhanced by toasting. To toast, spread sesame seeds in a thin layer in a shallow, ungreased pan. A pie plate works well. Heat in a 350 degree F oven about 10 minutes, stirring once or twice. It is best to store the seeds in the refrigerator or freezer because sesame seeds have a high amount of oil and they tend to go rancid.
