Saw a post about almond butter somewhere, and then I saw it was $8/jar plus shipping. Got me wondering if I couldn't make it myself, more cheaply and with control over the ingredients. Anybody done this?

I'm thinking of taking some unsalted almonds, putting them in a food processor and blending them with a little canola oil and maybe some Splenda.

If this works, I would also like to try a combination of almonds, pecans, black walnuts and maybe macadamias.

Any experiences? Thoughts? Think this is a nutty idea?
