Deep Purple – Celery root and Okinawan purple potato soup with crayfish
Deep Purple – Soupe de celeri rave et pommes de terre Okinawa aux écrevisses
Celery root reminds me of France and its Celeri Rémoulade…which is raw shredded celery root salad with mayonnaise. Not that I particularly like mayonnaise on salad but I love celery root flavor.
A while ago, my Japanese neighbor introduced me to this Japanese kind of sweet potato called Okinawan potato; it has such a beautiful vibrant purple color. She was telling me about all the wonderful nutrient packed in it and how they eat it in Japan, so it did not take me long to go and buy some. I love Japanese cuisine, and I was curious to taste it especially that it has many antioxidants, one of which gives it its purple color, is called anthocyanin.
In general I don’t eat much potatoes, I find them quite boring, but this one is really different from all the other kinds of sweet potatoes I tasted and I will explore its use further.
Now what do you do with a celery root and Okinawan potato? You can do many things but the cold weather made me decide on a soup.
The small cubes of potatoes and celery mixed to the crayfish add some pleasant texture to the soup, so that part is not optional. You can also use shrimps instead of crayfish.
This is a lovely soup, delicate yet fragrant with lots of character, so definitely a soup that I will make again.
