Basil seeds (sabja seeds) are tiny, black, oval-shaped seeds that swell into a gelatinous coating when soaked, resembling chia seeds. They have a mild, neutral taste and a soft, slippery texture, making them ideal for cooling drinks and desserts. Rich in fiber, antioxidants, and omega-3s, they aid digestion and hydration. Popular in Asian cuisines, they’re used in falooda, lemonade, puddings, and as a vegan thickener.
