I like to have simple syrup on-hand, especially during the summer when we drink a lot of iced tea, but I don't always remember to start it before I need it. It takes about 5 to 10 minutes to make it on the stove, and if you are almost ready to serve dinner, that's too long.
I tried using the microwave recently and found it makes a perfect simple syrup in just over a minute.
Instant Simple Syrup
1/2 cup sugar
1/4 cup water
Place sugar and water in a canning jar or other microwave safe container (not plastic) -- no lid. Microwave on high for one minute. Stir gently and carefully -- just stir it in the micro so you don't have to handle it twice. Microwave for another 20 to 30 seconds, until it starts to boil. Stop the microwave as soon as it starts to boil and rise, or you'll have a big mess. Carefully remove with a hot pad. Store leftovers in the refrigerator -- they last quite a while.
