Hemp hearts (shelled hemp seeds)
Hemp hearts are hemp seeds with the crunchy outer shell removed, leaving soft, ready-to-eat kernels at about 160 g per cup. They need no soaking or cooking — sprinkle them raw over yogurt, oatmeal, salads or blend into smoothies.
Their delicate oils are sensitive to heat, so add them at the end rather than baking them in, and keep the bag in the fridge to stay fresh.
