Combine sugar and water in a small saucepan and bring to a boil over medium heat. Be careful not to stir the mixture, but swirl the pot around regularly for roughly 15 minutes. Keep watching the mixture as it slowly turns from clear, to lightly amber, to darker amber shades. Once the color starts to darken, it happens quickly and you’ll want to off the heat before it goes brown (burnt). Have your cream and butter ready to go.
