What each ingredient does

Lump sugar
Caramelizes under heat to give the liquid its brown color and a slightly bitter, toasted flavor.

The step that matters

Stirring the sugar to bright brown. Sugar darkens quickly once it caramelizes. Going past the target colour makes the mixture bitter and burnt-tasting, so the browning should be stopped at the right shade.
