Nuts
Shelled
Shelled black walnut is commercial kernel stock ready for the pan or freezer—no cracker required. Convenience is high; oxygen exposure is immediate, so warm storage shortens life compared with sound in-shell lots. Taste should be bold and resinous; paint notes mean rancid refuse. Check for shell shards before serving children. Vacuum packs help only if kept cool after opening. Freeze for quality on long holds. Label as tree nut.

History
Indigenous peoples of eastern North America used black walnut for food, dye, and wood.
Settlers adopted black walnut as a regional flavour distinct from imported Persian walnuts.
Commercial cracking and ice-cream flavouring made black walnut a Midwestern specialty product.
Premium black walnut kernels and butters remain a US specialty rather than a global bulk nut.
