Purple Cabbage Soup – Cabbage Soup Recipe

Purple Cabbage Soup

I love Purple Cabbage for the colour and the crunch it adds to salads and coleslaw. I know that purple cabbages are often called red cabbages, but, the're purple, right? So I call them purple cabbages. I somehow ended up with two massive purple cabbages (not because I forgot I already had one and bought another. Well, maybe…).  I had to figure out what to do with them, so I came up with this Purple Cabbage Soup. It's pretty damn purple.

I know, the colour looks a little strange for a soup. However, the vibrant colour lives up to the promise of an equally vibrant tasting soup. And this soup is an amazing taste experience. Fennel and cardamom spice  up the sweetness of the cabbage, and give some warmth to the coconut milk base.

I buy or grow produce according to colour if I have a choice. Because the more colourful the produce is, the more nutrient dense it usually is. The gorgeous, vibrant colour of  purple (or red) cabbage indicates the abundance of antioxidants, flavonoids, and vitamin A in the crunchy cruciferous cabbage. Bonus: purple cabbage has twice the amount of vitamin C as green cabbage.

I knew it was nutritionally a healthier choice than green cabbage, but I was curious about how purple cabbage actually gets its lovely colour. According to Wikipedia, it all has to do with the PH value of the soil that the cabbage is grown in.  “In acidic soils, the leaves grow more reddish, in neutral soils they will grow more purple, while an alkaline soil will produce rather greenish-yellow coloured cabbages.”

Another interesting fact about the purple cabbage; it's juice can be used as a PH indicator because it contains anthocyanin, a pigment that turns red, purple or blue, depending on the PH.

My forgetfulness at the farmer's market led me to learn a few things I didn't know about purple cabbage, as well as a very pretty, very healthy, and delicious soup.

  1. I’ve never eaten a purple soup before…I’ve got to give this a try! I love purple cabbage and also add it to many of my dishes. I’ve added green cabbage to soups many times, but never once have I added the purple kind! Thanks for sharing 🙂

    1. Hi Kimberley, I was a little worried that it wouldn’t keep the vibrant colour after cooking, but luckily it was fine 🙂

  2. The colour of this soup is incredible! Great idea – I have never thought to make a cabbage soup with purple cabbage. The cardamom is a nice touch too, will have to try this next time I buy purple cabbage.

  3. As a natural-ingredient baker, I’m always looking for more veggies and fruit with which I can naturally dye and flavour my food. I LOVE the colour of this soup so much! I’ll have to test out purple cabbage juice as a dye next! 🙂

  4. What a gorgeous soup. I’m especially interested in the combination of black cardamom and fennel seed. I’d imagine that those play very well with the coconut milk.

  5. Colleen, I will totally try this and get back to you. The colour should be a hit with the kids and the nutritional value will score points with the naturopathic doctor in the house.

    1. Hi Edie, Apparently it’s been a big hit with kids from what I’m hearing! (A couple of adults have said they were grossed out by the colour, though, ha ha)

    1. Hi Zahra, Thanks so much for visiting! I’m working on installing a nutrition label on they recipes. So I’ll try to update you on the calories. But this soup is pretty low cal, because the only thing adding much for calories is the coconut milk, which is shared out with all the servings. And you can use light coconut milk to lighten it even further. Thanks for commenting 🙂
