How long does it take to make Biscotti?

Bake the logs a first time at 170–180°C (340–355°F) for 22–35 minutes, until firm to the touch and still pale; slice, and bake the slices a second time at a lower heat, 140–150°C (285–300°F), until dry and crisp.

How to Tell It's Done

until smooth and not sticky
until the logs are golden and firm to the touch
until the cookies dry out and brown lightly

Tips

Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
Slice with a serrated knife, in a sawing motion: a smooth knife presses on the log and crumbles the slices.

Common Mistakes

Check by the cue (until…), not just the clock: every oven bakes a little differently.

More Ways

Slice with a serrated knife: thin slices come out crisp, and slices about 1 cm thick are good for dunking in coffee.
The dough is a little sticky: shape the logs with wet hands and place them spaced apart on a baking sheet lined with parchment paper.
