Combine sugar and water. Over medium high heat, add sugar and 3 Tablespoon of water into a medium sauce pan. ***Do no stir. If need to, just swirl the pan.***Once the sugar dissolves, add lemon juice.
Let sugar turn amber. Let the sugar water simmer until an amber color, about 10-15 minutes, depending your heat level. ***Once the sugar starts turning yellow, it can burn quickly, so don't walk away.***
Add water and butter. Add the other ¾ cup of water immediately when the sugar turns amber. ***Sugar will bubble very violently for a few seconds.***Once the bubbling calms down, stir the sugar over medium heat until all dissolved. Take it off the heat and stir in the butter until thoroughly combined.
