I tried putting some dessicated coconut in my blender, but it was lumpy and tricky to remove (do use in cooking though still).

Were you trying to make coconut butter or coconut flour? I don't know how to make coconut flour, but I made coconut butter the other day in my wee little food processor and it turned out splendidly. The thing is that you have to keep scraping down the sides and pulsing. When done it should be pretty liquid and pour easily (until it cools down).

You also have to make sure that it isn't the "reduced fat" coconut or sweetened stuff--although that sounds like it wasn't the case for you. I'm guessing that you maybe just didn't keep at it long enough? You could also add a bit of coconut oil to get things going. I didn't need to do that, but I know that some people do. Check out videos on YouTube of people making coconut butter to get an idea of how long it takes.

Thanks - I was going for flour but got... lumps! I definitely need to invest in a new food processor of some kind. Would you recommend your one?

I've never made coconut flour. I think you need to separate the pulp from the milk first, though: http://www.ehow.com/how_5497666_make-coconut-flour.html Did you do that when you tried to make it? It kinda sounds like a big hassle to me. Have you looked on the Amazon UK store for coconut flour? That tends to be my go-to place for stuff like this (though I am in the US). Coconut flour is expensive, but I have found (in my very limited experience using it) that a little bit goes a long way.

My food processor is just a little cheapie one. Black & Decker, I think? It isn't anything impressive or high-powered (it gets hot easily, so I have to stop frequently) but it gets most jobs done.
