Preheat oven at 200℃. Wrap each beetroot tightly in foil and roast for about 1 hour. Remove from oven once they are tender, leave to cool and then peel the skin.
In a large cast iron pot, on medium heat, lightly toast the cumin seeds. Add the coconut oil and onions, and sauté until browned. Add the garlic and ginger, and sauté until mixture is fragrant. Add the roasted beetroots, coriander powder and chicken stock, and bring to a boil. Cover the pot, lower the heat and leave to simmer for 20 minutes.
Blend the mixture until it has a smooth and creamy consistency. Add the coconut cream and season with salt and black pepper powder. Simmer for an additional 5 minutes. Remove from heat and stir in lemon juice.
Garnish with pepper and pumpkin seeds. Serve either warm or chilled.
