Yes, it is possible to prepare nut pates using a household blender. Firstly, you need to remove the nut’s skin before preparing the pastes. This is going to be the hardest part, as well. However, a lot of the skin will get removed in the roasting process itself. Then you need to add the nuts into a blender. Do not add anything else into the blender, including oil or water. Keep in mind that it will take fifteen to twenty minutes to prepare the pastes, depending on the efficiency of your blender. If you want to add flavour to the pastes, you should do so after preparing the pastes.
