G: If you need a substitute for dark muscovado sugar, consider using one of the following options:

1. Light Muscovado Sugar: Use an equal amount, though it will be slightly less rich in molasses flavor.
2. Brown Sugar: Replace with dark brown sugar in equal amounts. It has a similar moisture and molasses content.
3. Molasses and White Sugar: For every cup of dark muscovado sugar, use 1 cup of white sugar plus 2 tablespoons of molasses.
4. Coconut Sugar: Use in equal amounts, although the flavor will be different.
5. Maple Sugar: Use in equal amounts. It has a unique flavor but can serve as a good alternative.

These substitutes should work well in most recipes, maintaining a similar texture and sweetness.
