Almond meal is much coarser and grainy than almond flour. On the other hand, the almond flour is much finer and suitable for baking and retains more moisture. The almonds used to make almond flour are first peeled and then grounded. Almond flour also has far less of the nutty flavour that the almond meal has which is made from unpeeled almonds. You can try making this recipe with almond meal, but you might have a tough time working the dough. But hey! Maybe they turn out great, in which case do let us know. Happy Baking!
