Nuts

Shell

The pecan shell is the thin-to-medium woody case around the kernel—easier to crack than black walnut, harder than some paper-shell marketing claims imply. It is not food, but it governs in-shell storage life, holiday cracking bowls, and how orchard nuts move to crackers. Home cooks crack shells for peak freshness; factories crack and aspirate before packing halves and pieces. Shell fragments are a dental hazard—inspect home-cracked meats carefully. Clean shells may be composted or used as mulch or craft fuel; never assume shell smoke is a safe food flavouring without knowing the material. Shell hardness varies by cultivar: paper-shell types open more easily, thicker types protect kernels longer in the shed. Sound in-shell lots often keep better than warm shelled halves because the shell limits oxygen. Keep shell grit out of flour mills and blenders.
