I’m still on a thin sliced biscotti kick, so here’s another version for you. This one is double chocolate and uses assorted nuts, white chips and chocolate chips. For the chocolate base, I just added 1 oz of melted unsweetened chocolate.
Another change I made was to halve the recipe (the full batch is below) and use a slightly smaller loaf pan. The batter didn’t go all the way across the pan, but since it’s fairly stiff I just pushed it up against one side so that it covered about 2/3 of the pan lengthwise. I’m mentioning this because this batch looks a little nubbier than the last and the reason was the halving. Anyhow, it’s fun having all this biscotti around. Hopefully I won’t be tired of it by Christmas, because it makes a great gift.
- 1 ounce unsweetened chocolate, chopped
- 4 large egg whites
- 1/8 teaspoon of salt, plus an extra pinch
- 1/2 cup plus 1 tablespoon (4 ounces) granulated sugar – weigh for best results
- 3/4 cup (4 oz) all-purpose flour – weight for best results
- 1/2 teaspoon vanilla plus a dash of almond extract if desired
- 2/3 cup mixed nuts
- 1/3 cup white chips
- 2/3 cup chocolate chips
- Preheat oven to 350 degrees F. Line a 9x5 inch loaf pan with strips of parchment paper or line with foil and spray foil with cooking spray.
- In a small custard cup, melt the chocolate in the microwave using 50% power and stirring every 30 seconds.
- In a metal or glass bowl, beat whites with a little of the salt until soft peaks form. Gradually beat in remaining salt and sugar; beat until stiff peaks form. Fold in melted chocolate and extract.
- Sprinkle flour over meringue mixture, and with a heavy duty silicone scraper, fold it in.
- Mix together the nuts and chips and fold them. The batter will be light brown, but the biscotti will be darker after they have gone through the whole baking cycle.
- Spoon the batter into your prepared loaf pan, spreading evenly. Bake on center rack for 35 minutes. Cool loaf in pan for about 20 minutes, then remove from pan and let it cool to room temperature. When it’s almost cool, transfer to the refrigerator and chill until very cold – this makes it easier to slice.
- Preheat oven again to 250 degrees F.
- Peel parchment off the cold loaf. With a serrated knife cut loaf crosswise into thin slices – mine are usually between 1/8 and 1/4 inch thick. Arrange slices on 2 baking sheets and bake for about 45 minutes (check at 30 minutes), switching racks halfway through. The goal is to dry them out without letting them get too brown, so keep a close eye on them. Remove from the oven and let cool. If they’re not completely crisp while hot, they should crisp as they cool.
