In biscuit making, nuts bring crunch and a large part of the aromatic profile. The difference often comes down to three factors: roasting, chop size and when they are incorporated.
1) Why roast nuts?
Roasting develops toasted notes and intensifies flavour. The result is a stronger sense of indulgence without adding more sugar.
2) Chop size = texture
- Large pieces: clean crunch, premium visual appeal.
- Small pieces: even distribution, finer texture.
- Powder: use sparingly, otherwise the dough can become drier.
3) Incorporation: avoid drying the dough
Add nuts once the dough is already homogeneous, and avoid overmixing afterwards. For very dry biscuits, prefer chopped pieces rather than nut powders.
FAQ
No, but it’s one of the best ways to intensify flavour. Even a light roast makes a big difference.
Most often because of too much nut powder (which absorbs moisture), or baking for too long. Prefer chopped nuts and watch the colour closely.
Roasted hazelnut is often the most expressive. Pistachio is very aromatic too, but shines best with a gentle base (vanilla, white chocolate).
