Maple sugar is a type of sugar that is prepared with the sap from a maple tree. To produce it, the sap is boiled until almost all of the water has been removed from it and the remaining product has crystallized. The sugar can be sold in large blocks, molded into small shapes or simply ground into a granulated version that can be used like regular sugar. It has a strong maple flavor and aroma to it, just like maple syrup.
Maple sugar can be used in recipes in the same way as cane sugar is used. It can be used to sweeten drinks, top oatmeal or incorporated into a flavorful rub for meats. When using maple sugar in baking, it acts just like regular granulated sugar and can be creamed with butter for cookies and cakes. It is almost twice as sweet as regular sugar, so when using it in a recipe that calls for regular sugar, you will want to reduce the amount of sugar slightly so that your finished product isn’t too sweet. You can reduce it by as much as half, but since you want the maple flavor to remain pronounced, it can be a good idea to use slightly more than half and adjust as you go.
