4. Heat milk at Medium setting until warm then add sugar. Bring to a rolling boil (Medium-High), stirring constantly with a wooden spoon. Continue to boil for 8 full minutes -or- if using a candy thermometer continue boiling until the boiling temperature reaches 235°F but do not exceed 9 minutes rolling boiling total.
