This is another dish that I served during the Xmas dinner. I am a huge fan of mushroom soup. As much as I remember, I used to survive on Campbell's mushroom soup during my school years. That and some instant ramen.

I had experimented, researched and tested my fair share of mushroom soups. Eventually, I had settled for Heston Blumenthal's version. I love how he adds potatoes to enhance the creaminess of the soup and also the stacking aroma from the addition of leeks.

I used a varieties of mushrooms instead of just one. There are so many to choose from, the wild expensive to the underrated cheaper ones. In the end, I used what I can get my hands on, shiitake and Swiss brown button mushrooms.
I love how Heston blitz some dried mushrooms into a powder and added them into the soup. It kicks this soup up a notch. Of cos, I added my own je ne sais quoi with some sauteed mushrooms and sacha inchi oil. Yes! Step aside truffle oil!
