How to make Honeycomb treats

Step 4 Hard crack test

If you have a sugar thermometer, superb, heat to the hard crack temperature. Most of us don't so the easy way to test is with the cup of cold water. Dip the end of the teaspoon in the syrup then into the cold water to set it. You might hear the sugar crack as it cools rapidly which indicates it's hot enough. Or just bite the syrup and if you can crack it off the spoon so that there isn't any left, then you're good to go. I find that it very quickly goes from "not quite hot enough" to "burnt", so move it off the heat while you check.
