Step 1: Prepare the Muffin Tin
Step 2: Make the Syrup
1/3 cup Karo syrup
Stir these ingredients in a microwave safe glass Pyrex pitcher and microwave on high for 5 minutes.
Stir with the candy thermometer and microwave on high for another 3 minutes. You want to get the temperature to 280 but not over 300. Microwave in one minute intervals to 280 degrees Fahrenheit.
Let the hot syrup cool to 250 before mixing in the flavoring. Carefully pour the syrup into the impressions in the powdered sugar. Let it cool before removing.
You can sift the powdered sugar and reuse it many times.
