Ingredients: 140g (1 cup) rye flour, 1-and-a-half sticks of salted butter, 124g (7/8) cup all-purpose flour, 3/4 teaspoon kosher salt, 1/2 teaspoon baking soda, 248g granulated sugar, 2 large eggs, 1 tablespoon molasses, 1 tablespoon vanilla extract, 105g (about 3/4 cups) semi-sweet chocolate chips, 105g white chocolate chips
Directions:
• In a 12-inch skillet over medium-high heat, toast the rye flour until fragrant and a shade or two darker, about 5 minutes, stirring frequently. Remove from heat, then add butter and stir until melted. Set aside to cool.
• Preheat oven to 350 degrees, with a rack in middle position. Line 2 baking sheets with parchment.
• In a medium bowl, whisk together the all-purpose flour, salt and baking soda
• In a large bowl, mix sugar, eggs, molasses and vanilla.
• When rye-butter mixture is cool to the touch, slowly stir it into the egg mixture. Add dry ingredients and stir until combined. Stir in chocolate chips and, if using, nuts.
• Drop 2-tablespoon mounds of dough about 2 inches apart onto prepared baking sheets. One sheet at a time, bake in preheated oven until edges are firm and centers are soft, 8 to 12 minutes, rotating sheet halfway through. Cool on sheet 5 minutes, then remove to a rack and cool 10 minutes. Repeat with second sheet.
