Ingredients
2 cups rye flour
2 cups all-purpose flour
1/3 cup sugar
1 teaspoon salt
1 large egg
2/3 cup buttermilk
Directions
Preheat oven to 350°F (175°C). In a large mixing bowl, combine the rye flour, all-purpose flour, sugar, and salt.
In a small bowl, beat the egg lightly, then mix it with the buttermilk until well combined.
Add the wet ingredients to the dry ingredients and stir until a stiff dough forms. The dough should be firm and slightly dry.
Turn the dough onto a lightly floured surface and knead gently for about 2 minutes until it comes together.
Shape the dough into a loaf approximately 3 inches wide and 2 inches tall. Place it on a parchment-lined baking sheet.
Bake for 25–30 minutes until the loaf is firm to the touch and lightly golden on top.
Remove from the oven and allow to cool for 10 minutes. Slice the loaf into biscuits approximately ½ inch thick.
Place the sliced rusks cut-side up on baking sheets and return to the oven at 300°F (150°C) for 15–20 minutes, stirring halfway through, until they are completely dry and crisp throughout.
Cool completely on a wire rack before storing in an airtight container.
Comments
This is a straightforward biscotti-style twice-baked cookie that uses six basic pantry staples available at any Charlotte supermarket, making ingredient hunting zero friction. At roughly 8 cents per rusk, it's genuinely cheap—driven by the high yield and bulk use of flour and sugar. The stated 70 minutes undersells the actual time: first bake is maybe 25 minutes, cooling is 10–15, then slicing into rusks and a second bake adds another 20–25, so count on closer to 90 minutes of real elapsed time, though hands-on work is modest. These reheat beautifully and store for weeks, making them excellent for a cookie jar or packed lunches, but they require decent oven attention during both bakes and are not the sort of thing a weeknight cook grabs on a whim.
