Sweet potato soup

I think everyone knows how to cook this. But the extra ingredient GINGER makes a difference as it soothes my stomach too. Thanks to Lily's blog for reminding me of this comfort food.

=Ingredients=

Sweet potatoes
Ginger
Sugar
Water


Method

1. Adjust the ingredients to your liking. Cut the sweet potatoes into cubes. Cut the ginger into slices. Add in the potatoes and ginger into a pot of water and let it boils.
2. When the potatoes become tender (when a fork can pierce through it), add in sugar and taste. 
3. Remove the ginger before serving the sweet potato soup. Enjoy it.
