The details that decide it
Skinning hazelnuts from the freezer
Hazelnut skins are bitter and most baking recipes want them gone. The freezer helps twice: freeze the nuts, toast them straight from cold until the skins blister, then tip them into a clean tea towel and rub — the loosened skins slide off in the friction. The cold-to-toast path gives a more even blister than toasting pantry-warm nuts, and the skins come away in bigger, cleaner sheets.
- Cold nuts toast more evenly than pantry-warm ones.
- Blistered skins rub off in a tea towel while warm.
- The skins are bitter, so baking usually wants them gone.
In-shell hazelnuts keep far longer than shelled ones
A hazelnut shell is a natural airtight wrapper, so nuts still in their shells will sit in a cool cupboard for months before the kernels inside begin to turn. Once shelled, the oil is exposed and the countdown starts, and a few months at room temperature is enough to stale them. That is the reason to buy in-shell when you can and crack as you go, freezing only the kernels you have already freed.
- The shell protects the oil, so in-shell nuts keep longest.
- Shelled kernels stale within a few months at room temperature.
- Crack as you go and freeze only the loose kernels.
How to tell a hazelnut has turned
A good hazelnut smells sweet and faintly woody; a bad one smells of old oil or cardboard and tastes flat and papery rather than rich. Hazelnuts go rancid rather than mouldy, so there is no fuzzy growth to warn you — the nose and the taste buds are the test. Rubbery kernels are merely stale and can be toasted into a bake, but a rancid one should go in the bin.
- Sweet and woody is fresh; old oil or cardboard is not.
- They turn rancid, not mouldy, so smell is the warning.
- Rubbery means stale and toastable; rancid means bin it.
