Pour a small amount of nuts on a flat plate, spread them, put in the microwave for 7 minutes on full power (have enough power). And times 2 would have to open and stop (though not necessarily). The nuts turn out super-duper! Rovnomerno fried and crispy! Recommend characteristics of the furnace: the Volume of 27l, the diameter of the tray 32, the power of microwaves 1100Вт. Well, there already based on the parameters of your furnace, consider, the smaller the power, the more time is needed.
