These yummy pecans are super for snacking, but they also make wonderful holiday or hostess gifts. Why use cane sugar? Cane sugar has a lower melting point than the more common beet sugar, which makes cane sugar better for candied glazes.
Spread pecans on a rimmed baking sheet. Place in oven for 5 to 7 minutes to lightly toast.
Meanwhile, for the spice mixture, in a small bowl combine the sugar, rosemary, salt, black pepper, and cayenne pepper; stir to mix. In an extra-large bowl, combine the melted butter and vanilla. Add the toasted pecans to the bowl with butter and vanilla; toss to coat. remove the pecans from the oven and add them to the butter and vanilla mixture, tossing to coat. Add the spice mixture; toss to coat evenly with spices.
Spread coated pecans to the same baking sheet. Bake for 8 to 10 minutes, until toasted and fragrant, stirring once halfway through. Sprinkle with additional salt, if desired. Cool pecans completely; they become more crisp as they cool. Store cooled pecans in an airtight container up to 1 week.
