Nut flours are often drier, because they are usually ground from dried cakes of nut that remain after nuts have been pressed to make oil out of them.
Meals are ground from whole nuts, so they’ll be oiler.
To make your own Nut Meal at home:
- You can mix the nuts you use, such as walnuts and pecans;
- Toast first to develop the flavour;
- (if you have time) freeze them;
- then pulse them (ideally frozen) in a food processor. Freezing them gives you a better chance of their not turning into a paste on you, though if you are are determined and overprocess them you can still end up with a paste.
Store in refrigerator, as it goes rancid even more quickly if you do not.
