Add some puffed amaranth to the bottom of your two glass and top with a couple of tablespoon of yoghurt. Top that with half the mango and then repeat to create another layer. Top with passionfruit and serve.
Puffed amaranth is also called popped amaranth. I haven't given exact quantities because you can just add an amount that suits you. For tiny babies, puree the mango rather than chop
