If you are lucky enough to get your hands on purple carrots and purple sweet potatoes at the same time – don’t miss out to use them for this Out of This World Purple Carrot and Purple Sweet Potato Soup. You can roast them too to side with something – but this soup really is out of this world. These are called heritage carrots and potatoes.
What are heritage varieties?
Heritage or heirloom carrots come in other colours too, not just orange: purple, yellow and even black. They are called heritage varieties because this is how carrots used to be before Dutch growers developed a uniform orange variety (supposedly in honour of their national colour).
When it comes to the purple sweet potatoes, they are a specialist variety. They are called Okinawan sweet potato. These are originated in Central and South America.
Do purple carrots and sweet potatoes taste differently?
Yes.
They are sweeter than the orange ones, both of them. The carrots have a a sweet, almost peppery taste and the sweet potatoes are sweeter in taste too. They are both quite intense in this sweet taste as opposed to the orange varieties. As you would expect the same from different colours of fruit and vegetable varieties.
Which means your soup will taste not quite savoury as you are used to, when using the orange variety of vegetables. Which is why the coconut and chilli works so incredibly well in this flavour combination.
They are both rich is anthocyanins, which is responsible for their rich purple colour. You can find anthocyanin in other very intense blue and purple hues with edible plants like red onion or blueberries.]
Good news is, they are more nutritious than the orange ones and being cooked is even better – as you might already know that: cooked carrots are 3x more nutrient dense than raw carrots.
Enjoy!
