Step 2
Set your microwave cooking power to 500 watts. Microwave caramel sauce for 2 minutes. Stop microwave and then microwave at 10 second intervals (still at 500 watts), checking the sauce after each 10 seconds, until caramel starts to turn color. About half of the sauce should turn a light amber color while the rest remains clear. (It should take between 3 minutes to 3 1/2 minutes total cooking time including initial 2 minutes to reach this color).
