Toasting nuts (and seeds) brings out their flavor and aroma. Toast in a 170c, spread on a baking sheet in a single layer, for about 3 to 5 minutes. Watch carefully because as soon as they start to color they could be toasted very quickly. Remove them from the baking sheet as soon as you take them out of the oven, otherwise they will continue browned. If you want to remove the skins from the nuts, wrap the toasted nuts in a kitchen towel. Let the nuts steam for 5 minutes. Roll the nuts around (while still in towel) until skins rub off.
