Nuts

Shell

The pine-nut shell is the hard woody case around each seed—thin on some species, stubborn on others. Harvest means extracting seeds from cones first, then cracking shells; labour explains much of pine-nut price. Shells are not food. Home cooks almost always buy shelled kernels because cone and shell work is specialised. Shell fragments left in packs are a dental hazard—inspect carefully before pesto. Clean shells may be composted or discarded; they are not a stock vegetable. Species differ: pinyon shells are thick relative to tiny seeds; commercial Korean-pine shells are handled industrially at scale. Sound in-shell seed is uncommon in Western grocery compared with shelled bags. Keep shell grit out of blenders and mills. The shell’s main role is protection during trade before the fragile oil-rich meat is exposed.
