I am constantly overwhelmed by the surprising depth of flavour of this simple little soup, the beauty of this soup – it’s simplicity and bare ingredients. You just would not believe something so basic could taste so rich and deep AND creamy! Those macadamias are just pure magic in this soup.
Peel the sweet potato and cut into rustic chunks with the red onions.
Toss the vegetables in olive oil and Celtic sea salt.
Roast in a slow oven for about 1 hour so as not to get any burnt black bits.
Bring stock to the boil. Add in roasted vegetables and simmer for about 10 minutes.
Allow to cool slightly, and then blend in batches with the raw macadamias.
Return to the stove, and simmer for a further 5 minutes. Season with Celtic sea salt to taste.
Garnish with some chopped coriander and some raw macadamias and devour!
It is worth mentioning that I have made this soup in Australia and in the States, and it was quite different, due to the quality and variety of the sweet potatoes. They have a much bolder and richer flavour in Australia. If you are making this in the U.S use yams or orange sweet potatoes. You will also probably only need 1/2 cup of macadamias, and then taste your soup before you add the second 1/2 cup. Experiment and you will find your perfect blend.
I will say that you will get a more creamy soup if you use a high-speed blender like a Vitamix. You might find that a stock standard blender doesn’t quite “cut the mustard”. But you will still get the taste sensation.
