Combine all ingredients (except flavoring) in a medium size pot

Cook on stove over high heat until your mixture reaches 300°F or until it reaches hard crack on a candy thermometer.

Once mixture has reached the desired temperature, add flavoring (keep you face a safe distance from the mixture or you will burn your eyes)

Cover a cutting board with powdered sugar (maybe do this before you begin cooking) and pour liquid candy onto cutting board. I suggest placing a large piece of foil under the cutting board in case your candy spills over the edge. Do not touch the candy. It will be very very hot.

Once your candy is at a point where it is pliable but not gooey, take a knife and begin cutting into squares. Again, don't touch it with your hands because it will still be very hot. Note: you do not have to cut all the way through

Once candy has completely cooled, break up the small squares and enjoy

You may also use a hard candy mold (generally white in color) just make sure you grease it first. In that case just pour the candy into the mold and wait for it to cool completely.
