Gadget Post – Mortar and Pestle

I’ve been wanting a bigger M&P set.  I have a small ceramic one that is too small for anything more than the odd clove or a teaspoon of seeds.
They require a break in process before being considered ready for duty. They recommend that you grind some rice to powder in it.
Unlike the advice in the link, the  makers of my new set recommend grinding the rice dry several times – until the powder is white. This in the first grind, I’ll go another one or two and call mine done.
