When to choose Black Treacle on Slimming World

Common Slimming World mistakes with Black Treacle
The classic mistake with Black Treacle is the knife scoop, not the level teaspoon. A casual scoop on toast is usually 2 to 3 teaspoons of spread, not 1 — which can triple the syn cost of breakfast without you noticing. Measuring once with a level teaspoon shows you what the portion really looks like and makes future spreading much more accurate.
