Move over nut flours, there’s a new kid in town — gluten-free, grain-free Otto’s Naturals Cassava Flour. It’s the key ingredient in this Cassava Flour Biscotti, and perfect for many other recipes where you’d typically use wheat flour.
Now if you’ve heard of cassava but aren’t quite sure what it is, here’s quick overview. Cassava is a tuberous root vegetable also known as yucca. Similar to sweet potatoes and other starchy roots, it is a staple in Africa, Asia and South American. Unlike tapioca, which is extracted from the cassava root, cassava flour is made by grinding the whole peeled root.
As for the Otto’s brand, it has kind of a fun story behind it. Otto’s Naturals was founded by Sadie and John Olsen who dealt with their own food sensitivities by traveling the world and tasting new and unusual foods. They “fell in love”with cassava in Brazil, and subsequently developed a special method for making a very clean tasting, smooth textured cassava flour that measures 1:1 in many wheat flour recipes.
Otto’s really does have a fairly neutral flavor, and it’s fun to play with because it is so easy to substitute for wheat flour. So far I’ve used it in cookies, chocolate cupcakes a quick bread (that one didn’t work out so well) and this biscotti. Using cassava flour is fairly simple, but I do recommend weighing it rather than measuring by volume. It’s very soft and dusty, so it doesn’t always settle the same way in a measuring cup. Experiment! Maybe try some of the recipes from the Otto’s website first. Or try mine! It’s a crunchy, no-oil, no-butter biscotti made with coconut sugar.
Otto's Cassava Flour Biscotti
- 1 1/3 cups Otto’s Naturals cassava flour 170 grams -- I measured by weight
- 3/4 teaspoon baking soda
- 1/4 teaspoon salt
- 2 large eggs
- 2/3 cup coconut palm sugar 80 grams
- 1 teaspoon pure vanilla extract
- a little water optional
- 3/4 cup roasted unsalted almonds optional but recommended
- Preheat oven to 300 degrees F. Line a cookie sheet with parchment paper.
- Stir flour, baking soda and salt together in a mixing bowl. Set aside
- In a second bowl, using an electric mixer, beat the eggs until light and foamy. Add the sugar and vanilla and beat for another minute.
- Stir the dry ingredients into the liquid ingredients. If the dough seems dry, add water one teaspoon at a time until it comes together. You may not need any.
- Add the nuts (if using) and using your hands, knead them into the dough so they are evenly distributed. The dough will be thick, yet pliable and easy to shape.
- Shape the dough into a 10 x 2 1/2 inch log directly on the baking sheet.
- Bake log at 300 degrees F. for 40 minutes. It will spread a just a bit and the top should crack slightly. Remove from the oven and let cool for about 5 to 10 minutes.
- Transfer log to a large cutting board and using a sharp knife, cut the log every 1/2 to 3/4 inch on the diagonal. Stand the cut biscotti on the baking sheet and bake at 300 for about 20-30 minutes. If you sliced the biscotti thinly (1/2 inch thick or less) check at 20 minutes.
- Let cool on a wire rack. It should crisp as it cools.
