Yes, it's salt.
Yes, it's pink.
This pink salt comes from inland Australia. Its produced naturally from evaporated ground water that is high in mineral content & the colour comes from a salt tolerant algae which secretes carotene. We've started using this pink salt in our cooking & it does make a difference. Its not as harsh as your normal table salt and has a more delicate flavour.
And its also good for the environment by helping to reduce the salinity of the inland waterways.
