Ground pistachios ?

[GezFox]

I have a recipe for a pistachio and lime cake which calls for ground pistachios. anyone seen the in the supermarkets ? Struggling to see them online. I guess I could stick whole ones in food processor ?

I have never seen them - I make Baklava with them, and have to grind my own. I buy the shelled ones from Indian supermarkets - they work out quite a lot cheaper than elsewhere :)

I think that they lose their flavour quickly so are usually sold whole, in their shells.
