No fat, by design

Butter shortens a biscuit, coating flour proteins so they cannot form long gluten chains, and the result crumbles under your teeth. Biscotti leave the fat out entirely, so a modest gluten network does form and the dough bakes into something firm and cohesive. The second bake then drives off the remaining moisture, and the sugar dissolved in it recrystallises into a hard glassy matrix as it cools. That is what makes them snap, and what makes them keep for a month.

Notes

  • Cut with a long serrated knife using a single sawing stroke. Pressing down fractures the log.
  • Space the slices out on the second bake. Crowded, they steam each other soft.
  • If they still bend when cool, give them another eight minutes at 150°C.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
