FAQs
Can I use raw beetroot instead of cooked?
Using cooked beetroot is best as it softens the texture and brings out its natural sweetness. Raw beetroot may result in a grainier soup and longer blending time.
What can I substitute for onion seeds if I don’t have any?
If you don’t have onion seeds, you can use nigella seeds, cumin seeds, or even a pinch of onion powder to add a similar savory note to the soup.
