This ginger syrup can be used to flavor just about anything, but we love adding it to plain seltzer for homemade ginger ale.
Place sugar, ginger, and 2 cups water in a medium saucepan; bring to a boil. Reduce to a simmer, and cook about 1 hour, until ginger flavor is quite strong. Let cool; strain before using. Store in an airtight container, refrigerated, up to a week.
