Neither overtly salty nor sweet, and with a pleasantly grainy texture, these biscuits won a loyal following on Herron Island.
1 and 1/4 cups all-purpose flour
1 and 1/4 cups whole-wheat flour
1 and 1/4 cups cornmeal
1 and 1/4 cups old-fashioned rolled oats
1/2 cup toasted wheat germ
1/2 cup packed light brown sugar
1 tablespoon baking powder
1 and 1/2 teaspoons salt
1 and 1/2 sticks (3/4 cup) cold unsalted butter, cut into tablespoon pieces
1 cup plus 1 tablespoon water
1/2 cup chopped fresh flat-leaf parsley
1/2 cup chopped fresh mint leaves
1 large egg
Pulse flours, cornmeal, oats, wheat germ, brown sugar, baking powder, and salt in a food processor until combined. Add butter and pulse until mixture resembles course meal with pea-sized butter lumps. Add 1 cup water and pulse until a course, dense dough forms.
Turn out onto a lightly floured surface and knead in parsley and mint until well distributed. Gather, then halve dough with scraper. form into 2 balls and flatten each into a 6-inch disk.
Put oven racks in upper and lower thirds of oven and preheat oven to 350 degrees. Grease 2 large baking sheets.
Roll out 1 disk of dough into a round (1/3 inch thick) on a well-floured surface with a well-floured rolling pin. (If dough becomes too soft to roll out, wrap in plastic and chill until firm.) Cut out as many biscuits as possible and arrange about 1/4 inch apart on 1 baking sheet. You can find doggie bone shaped cookie cutters at 'Pet Smart' on online.
Gather scraps and reroll, then cut out more biscuits. Repeat with remaining dough, using other baking sheet.
Whisk together egg and 1 tablespoon water. Brush biscuits with egg wash and bake, switching position of sheets halfway through, until tops are golden brown, about 35 minutes total. Turn off oven and dry biscuits in oven overnight.
Tootsie's Notes: Biscuits keep, layered between sheets of wax paper or parchment, in an airtight container at room temperature one month.
