Nuts

Kernel

The walnut kernel is the edible brain-shaped seedmeat of Juglans regia after the shell is removed—the default form recipes mean by “walnut.” Fresh halves taste sweet-bitter and rich under a tannic pellicle; the crunch should be clean, not mealy or greasy-stale. This is the stock that becomes snacks, salads, baklava layers, pesto-style sauces, meals, and pastes. Sort out dark, shrivelled, or paint-smelling pieces before grinding so one bad nut does not spoil a batch. Light toasting blooms aroma and softens raw astringency for cold dishes; some kitchens blanch to reduce pellicle bitterness and pale colour. Freeze halves and pieces if turnover is slow—the polyunsaturated oils do not forgive a warm pantry. Compared with pecan, kernels are more tannic; compared with black walnut they are milder. Major tree-nut allergen handling applies. Buy recent harvest when possible and taste before committing expensive pastry to a rancid bag.
