Brown Sugar or White Sugar for Toffee?

Both work — white sugar gives a cleaner caramelized flavor and lighter color, while brown sugar's molasses adds deeper, butterscotch-like notes and a darker toffee, so the choice is about the flavor you want rather than success or failure.

What it means

White granulated sugar caramelizes to a clear amber and lets the butter flavor come through cleanly.
Brown sugar contains molasses, which adds moisture, acidity, and a richer, more toffee-forward taste plus a darker color.
Many classic English toffee recipes use white sugar or a blend; some cooks add a spoonful of molasses to white sugar to get the best of both.

Risks & deadlines

Brown sugar's extra moisture and acidity can slightly change cooking time and make the mixture more prone to separating, so stir steadily.
Because brown sugar is already dark, it can hide the visual color cue for doneness — lean on temperature or the cold-water test.
