Purple Yam Soup

First I would like to apologize for the long absence from the blog. It was a combination of many things that has kept me away from the blog but I am back with a new recipe πŸ˜€

The holy month of Ramadan started on July 9th. It is a time of reflection, prayer and spiritual enlightenment. But since the fast is about 17 hours long where I am, it is important to select the right food for those who are fasting when they are opening their fast in the evening. The evening meal is called Iftar. The food must be soothing to the tummy and taste good. So when I am cooking for my family, I look for something that is flavourful, delicious yet easily digestible.

A soup can often fit the bill! It can be flavourful and filling. The soup recipe I am sharing with you really comes from my love for colourful food. Last summer when browsing the vegetable section of the local Chinese grocery, I can across various different types of yam and sweet potato. Now I am not a 100% sure if the correct name is purple yam or purple sweet potato. The confusion stems from a conversation with my Dad who is an agronomist. Being the child of an agronomist and botanist, it has been drilled into be from early childhood to identify plants, vegetables and fruits by their correct names. If you know what the correct name is, do drop me a line in the comments section below.

Okay, so I digress. Back to the story of this soup. I just couldn’t leave the colourful yam at the store. As usual, I was unsure of what I wanted to make with it. When I was back at home, I thought on it and looked into my fridge and pantry, which are stocked with ingredients from various parts of the world. I found this tin of tom yum paste that my Mom had just gotten from me from a street vendor in Bangkok, Thailand. I decided I would try making a soup using the paste. The soup I made that day has evolved into the following recipe. Hope you enjoy this soup as much as we do at home πŸ˜€
