How to measure hazelnuts accurately
For the most reliable baking results, weigh hazelnuts on a kitchen scale rather than scooping by volume. One US cup of hazelnuts weighs about 135 grams (4.76 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts hazelnuts and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Roast hazelnuts at 180°C until the skins crack, then rub them in a clean tea towel to remove the bitter skins before using.
