Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Triple-chocolate Biscotti
Ingredients
Directions
Prepare the dough
Line a large baking sheet with double thickness of foil.
Sift in salt, baking powder, cocoa, and flour into a large bowl to blend.
Beat in eggs one at a time, then vanilla.
Beat in flour mixture.
Stir in chocolate and white chocolate chips by hand.
Heap dough into two long strips.
Refrigerate for 30 minutes.
Bake and slice
Bake at 350°F for about 25 minutes (until tops are cracked).
Let cool for 10 minutes.
Reduce heat to 300°F.
Using foil as an aid, lift logs onto work surface.
Cut logs into 3/4‑inch pieces, arrange half of slices (cut side down) on each prepared baking sheet.
Bake biscotti until just dry to touch (about 8 minutes).
Turn biscotti and bake again for another 8 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the dough together as it bakes.
- Eggs
- Bind the dough and set during baking, giving the biscotti their firm crumb.
- Unsalted butter
- Adds fat for tenderness and richness in the crumb.
- Baking powder
- Releases gas during baking so the dough rises and lightens.
- Semi-sweet chocolate chips
- Add melted-chocolate richness and deep flavor throughout the biscotti.
- Unsweetened cocoa powder
- Gives the dough its chocolate flavor and deep color.
The step that matters
Slicing and second bake. The logs must cool briefly so they can be cut cleanly without crumbling. The second, lower-heat bake after slicing dries the pieces out, which is what makes biscotti crisp rather than soft.
