Why are my cinnamon sugar pecans soft instead of crisp?

The syrup almost certainly left the heat too early, while it was still glossy. The coat must turn matte and sandy in the pan for it to set crisp. Return the batch to a dry skillet over low heat, stir about 1 minute until the shine dies, then cool again on fresh parchment.

How do I keep candied pecans from sticking together?

Speed at the sheet pan is the fix. Scrape the nuts out the second the pan leaves the heat, spread them in a single layer, and separate clusters with two forks before the coat sets. Once fully cool and crisp, they break apart cleanly and stay separate in the jar.

Can I make cinnamon sugar pecans without brown sugar?

Yes, use all granulated sugar and add an extra pinch of cinnamon. The crystallization is actually a little crisper. What you lose is the molasses depth and amber color, so the flavor reads simpler and sweeter. A drop of molasses in the syrup restores most of it.

Do I have to toast the pecans first?

It is strongly recommended. Three to four dry minutes in the skillet deepens the nutty flavor and drives off surface moisture, so the syrup coats instead of steaming. Skipping the toast gives paler flavor and a slightly softer center under the crisp shell.

How long do cinnamon sugar pecans keep, and can I freeze them?

Stored airtight at room temperature, they keep their crunch for up to a month. For longer storage, freeze up to 3 months and thaw the sealed container at room temperature before opening, so moisture condenses on the jar rather than on the nuts.

Instructions

Line a rimmed baking sheet with parchment. Add the pecans to a large dry skillet over medium heat and toast, stirring often, for 3 to 4 minutes until fragrant and a shade darker. Tip them into a bowl.
In the same skillet, combine the granulated sugar, brown sugar, water, cinnamon and fine salt. Stir over medium heat until the sugars dissolve and the syrup bubbles across the surface, about 1 minute.
Return the warm pecans to the skillet. Stir constantly with a wooden spoon for 3 to 4 minutes, until the syrup thickens, turns matte and sandy, and coats every nut in a pale, grainy layer.
Take the pan off the heat. Add the vanilla and the cayenne if using, and stir for 15 seconds as the vanilla steams and perfumes the batch.
Scrape the nuts onto the parchment in a single layer. Separate any clusters quickly with two forks and shower over a pinch of flaky salt.
Cool for 10 minutes without touching them. The coat sets hard as it cools. Break apart any remaining clusters and serve or jar.
