Chopped hazelnuts weigh 115 grams per cup, and hazelnuts are unusual among common baking nuts for the thin, bitter brown skin that clings to the nut meat — a skin most recipes specifically call for removing (typically by toasting the nuts and rubbing them in a clean towel) since it carries a noticeably bitter, slightly astringent flavor that most bakers don't want in a finished dish.
Hazelnuts' natural pairing with chocolate is deeply rooted in food history and geography — the combination is central to Piedmont, Italy's culinary tradition (home to both a major hazelnut-growing region and the origin of gianduja, a chocolate-hazelnut paste dating to the early 1800s), a pairing that eventually gave rise to the mass-market chocolate-hazelnut spreads familiar today.
Turkey grows the overwhelming majority of the world's commercial hazelnut supply, a fact that occasionally surfaces in the news when weather events affecting Turkish harvests ripple through global hazelnut and hazelnut-spread pricing — a level of supply concentration few other common nuts share to the same degree.
Rubbing warm toasted hazelnuts together in a clean towel loosens most of their papery skin in just a minute or so of effort.
A quick pulse in a food processor gets chopped hazelnuts to a fine, even texture for baking, though pulsing too long risks turning them into a paste rather than distinct pieces.
Hazelnut oil, pressed from the nut, has a distinct, rich flavor used sparingly as a finishing oil rather than for cooking at high heat, since its delicate aroma fades quickly under direct heat.
Hazelnut flour, made by finely grinding blanched hazelnuts, is a popular gluten-free baking ingredient that adds real hazelnut flavor and moisture to a cake or cookie, distinct from a coarser chopped hazelnut used as a topping or mix-in.
Toasting whole hazelnuts before chopping intensifies their flavor considerably and is also the easiest way to loosen their bitter skin for removal, combining two useful steps — flavor development and skin removal — into a single process.
Frequently asked questions
Do I need to remove the skin from hazelnuts before using them?
Most recipes call for it, since the thin brown skin carries a bitter, astringent flavor most bakers want to avoid — toasting the nuts briefly and rubbing them in a clean kitchen towel removes most of the skin easily.
Why are hazelnuts and chocolate paired so often?
The combination has deep roots in Piedmont, Italy, a region that grows hazelnuts and originated gianduja, an early chocolate-hazelnut paste, a pairing tradition that eventually led to the mass-market chocolate-hazelnut spreads popular worldwide today.
Where do most hazelnuts sold in the US come from?
Turkey grows the large majority of the world's commercial hazelnut supply, with Oregon's Willamette Valley being the primary US-grown source — a geographic concentration that can noticeably affect hazelnut pricing when either region has a difficult growing season.
Are hazelnuts and filberts the same thing?
Yes — "filbert" is simply an older, still-used alternate name for the same nut, more common in some US regions (notably the Pacific Northwest) than others.
Does toasting change the weight-per-cup figure for chopped hazelnuts?
Slightly — toasting drives off a small amount of moisture, which can make toasted hazelnuts marginally lighter per cup than raw, though the 115g figure works as a reasonably close reference either way.
