On a parchment-lined sheet tray, toss the nuts in the oil and season with a few pinches of salt. Bake 12-15 minutes, until just becoming fragrant and slightly darkened in color.
While the nuts bake, mix together the maple syrup and spices.
Drizzle the maple syrup mixture over the nuts, toss, then return to the oven for 10-15 minutes more, or until the maple syrup has thickened and is just beginning to crisp and harden on the nuts.
Remove nuts from the oven and allow them to cool completely—cooling will allow the sugars to harden and dry out. Store in an airtight container for up to 2 weeks.
