The 15-minute soup using ‘healthiest vegetable on Earth’ that’s the perfect winter warmer packed with nutrients
AN UNDERRATED superfood has been hailed as the healthiest vegetable on Earth - and it creates the "most delicious" soup.
You'd be forgiven for assuming that kale or spinach would top the list for number one veg.
But it's actually the humble watercress, packed full of nutrients, that has received the top gong from agriculture and nutrition experts.
The Centre for Diseases and Control () assigns nutrition density scores to foods based on their concentration of essential vitamins and minerals.
And the only vegetable to earn a perfect score of 100 is watercress, making it the healthiest veg in the world according to .
The superfood is low in calories, fat free and packed with vitamins and minerals.
To introduce watercress to your diet, TV chef recommends a simple soup that is a "bowl of health" on a winter's day.
The best part? It takes less than 15 minutes to make from prep to cooking.
Speaking on his BBC show Kitchen Secrets, Raymond says: "I love watercress. I use it in many ways, not just meaningless garnishes but in my food whether it’s herb purees or soup. There’s so many wonderful ways to use it.
"It is a very strong flavour packed with masterful flavours and pepperiness, it is absolutely delicious.

"Watercress should have a much bigger place in our [kitchen] than just being a garnish."
To make the watercress soup, melt some butter in a saucepan and cook half a chopped onion and one garlic clove for three minutes.
Then increase the heat and add 300g of watercress alongside a pinch of salt before covering with a lid and cooking for 30 seconds.
Next up, add around 100g of spinach and cook for a further two minutes, or until wilted.
Pour in 500ml of boiling water after this and simmer for three minutes.
Raymond then hails his next step as his "little secret" to get the most flavour out of the veg.
He says: "I stop the cooking [process] with ice. That’s a little secret so you can retain the flavour, colours, texture and nutrients."
For this recipe, 500g of ice is enough to lock in the vitamins, minerals and flavour.
