North Carolina chef Vivian Howard always keeps a jar of these addictively sweet and spicy pecans on hand. Fold her secret spice mix into beaten egg whites, which will coat each nut with flavor and a sugary crunch.
Preheat to 350 degrees F. Whisk egg whites until they are doubled in volume and stick to the whisk (just before "soft peak" stage). Gradually whisk in sugar and salt. Add spices: paprika, chipotle, cumin, paprika and coriander. Whisk to combine. Add pecans, then use a rubber spatula to toss, coating the nuts evenly.
Line a baking sheet with parchment paper and spread nuts in a single layer. Bake on the middle rack for 10 minutes.
Remove baking sheet. Use a spatula to flip pecans, breaking up any clumps, working quickly so they don’t lose their heat. Bake an additional 10-20 minutes. (Total baking time will vary depending on size and moisture content of nuts.) When pecans are ready, they will be dark brown; when tapped with a spoon, they should sound dry and flat. Remove from oven and cool before serving. Pecans will keep for 2 weeks at room temperature stored in an airtight container.
