Steps
Mix · About 7 min
- Heat oven to 180°C / 350°F. Mix 250 g plain flour, 140 g sugar, 2 eggs, 40 g melted butter, 1 tsp baking powder, 120 g almonds, 5 g orange zest into a stiff dough; shape two logs on a lined tray.
Check: The food must be hot through at 180°C / 350°F.
First bake · About 25 min
- Bake 25 minutes until firm. Cool 15 minutes, then cut into 1.5 cm slices with a serrated knife.
Check: Look for this result: firm.
Dry · About 10 min
- Lay slices flat and bake 10 minutes per side at 150°C / 300°F. Cool completely on a rack.
Tips
- Let logs cool slightly before slicing to reduce crumbling.
- Use the texture and doneness checks in the method; cooking times depend on your pan and heat.
Substitutions
- Use hazelnuts instead of almonds.
Storage
- Cool promptly; refrigerate covered within two hours, or one hour above 32°C / 90°F. Keep at 4°C / 40°F or below and use within two days.
- Keep cream, custard, cheese and meat fillings refrigerated. Reheat savoury filled dishes to 74°C / 165°F; serve chilled cakes directly from the fridge.
Make ahead
- Prepare the measured ingredients for Biscotti one day ahead. Refrigerate chopped vegetables and other perishable ingredients separately; complete the staged cooking on the serving day.
