Unfortunately, it becomes very common to have someone among our relatives touched by cancer. So if the food we eat can help, there’s no hesitation to have! Among superfoods, turmeric is one that can be used in so many preparations such as soups as here, meat stew, roasted vegetables, salad dressing…

Information on turmeric

Turmeric belongs to the ginger family. The root is ground into powder. Marco Polo described turmeric as “a fruit looking like saffron and almost as useful as saffron”. Turmeric was first used in Europe as a substitute for saffron then for its own properties, its delicately musky fragrance, and its deep orange-yellow, almost ochre color.

Among the benefits of turmeric: it contains curcuminoids, a very powerful antioxidant helping to prevent cancer and contributes to its treatment. Turmeric also helps to fight stomach ulcers, helps the nervous system function properly (thus preventing Alzheimer’s disease), reduces cardiovascular diseases risks, stimulates the immune system. It is also anti-inflammatory and anti-coagulant… I hope you’ve understood my point. I won’t describe each benefit of turmeric but the one thing that is for sure, if you like its taste, don’t hesitate!


Watercress has a nice peppery taste and is rich in vitamins A, B9, C, and manganese. It is also a source of calcium and iron. You can cook it in soup as here or for instance in substitute to basil to make pesto, I’ve posted a recipe on the blog, check it out!

The tip of the recipe

Have you seen this bright green color? I have a secret and will explain to you how to make the perfect watercress soup. It’s actually due to the combination of the turmeric orange – ochre color and my little trick:

If you don’t want your watercress soup to become dark green or yucky (in French we literally say “goose poo”, you see the color I mean?), watercress leaves don’t have to cook long. The soup is cooked with watercress stems, allowing the preparation to get the tasty peppery flavor of the watercress. Then at the very last moment, just before mixing, leaves are thrown in the soup and the soup is immediately mixed. Use the same trick for carrot top soup for example.

If you love soups as much as I do, as it’s a dish I cook very often, I have several soup recipes on the blog here. The iconic onion soup of course, and also pumpkin soup with pain d’épices gingerbread croutons or classic leek and potato soup.
