Sweet Potato & Ginger Soup
This sweet potato & ginger soup (番薯老姜糖水) certainly warmed our tummies and soul when we enjoyed a hot bowl on a rainy day. I have been cooking & eating more sweet potatoes these days, because the past 2 months of working from home has made me put on weight T_T Sweet potatoes help keep me full, while aiding in weight loss due to its lower Glycemic Index (GI) at the same time.
My version of this Chinese sweet soup (糖水) is extra spiced and delicious, due to the addition of pure (Bentong) ginger powder. Check out the ingredients & step-by-step photos in this post.
Main ingredients: Sweet potato (orange/yellow flesh), ginger, black sugar (I used this jaggery sugar from Sheng Siong), pandan leaves …
Lightly smash the ginger with a mortar & pestle (pictured above) or the flat part of a chopper. After this, I placed the ginger in a disposable soup pouch (optional) for easy removal & in case there are small bits of ginger in the soup.
Add all the ingredients (including sugar) into the pot.
Bring to a boil for 15 to 20 minutes (with a small lid vent opening), until the sweet potato is just done. Do not boil for too long as the sweet potato will become mushy & disintegrate easily.
As a special finishing touch, I added a small amount of pure ginger powder to taste. This ingredient is optional, but it made a huge difference: the sweet potato soup tasted extra spiced, warming and delicious. I bought my bottle from Malaysia before the lockdown, but you can still find pure ginger powder in some Chinese organic food shops in Singapore.
