Ingredients:
Rum Balls
1 box (11 ounces/310 grams) Nilla wafers
1 cup(120 grams) unsalted raw or toasted pistachios
1 cup(120 grams) confectioners’ sugar
1/4 cup(20 grams) unsweetened cocoa powder, sifted
1/2 cup(120 milliliters) spiced rum, like Old Monk or Captain Morgan
1/4 cup(60 milliliter) runny honey
1 teaspoon(5 milliliter) vanilla bean paste or extract
Zest of 1 orange, optional
To Roll
2 cups(240 grams) confectioners’ sugar, sifted
2 tablespoonscornstarch
Directions:
In a food processor, pulse the wafers on high speed until finely ground. Sift through a fine-mesh sieve held over a large mixing bowl. Return any coarse bits to the food processor and pulse until fine. Return the wafer powder to the large bowl.
Add the pistachios and pulse for a few seconds on high speed until the nuts are coarsely ground. Add the ground nuts to the large bowl. Add the confectioners’ sugar and cocoa powder and whisk to combine evenly.
In a small bowl, whisk the rum, honey, vanilla bean paste, and orange zest until the honey is completely dissolved. Pour this liquid into the large bowl and fold with a silicone spatula until the mixture absorbs all the liquid and there are no visible dry flecks. Cover and let sit for 10 minutes.
Make the confectioners’ sugar mixture for rolling: Whisk the confectioner’s sugar and cornstarch in a mixing bowl. Line a baking sheet with parchment paper.
Divide the rum ball mixture into 25 equal parts (about 1 heaping tablespoon/30 grams each). Shape each into a 1-inch (2.5-centimeter) ball using your hands. Place a few balls (5 to 6) at a time in the confectioners’ sugar mixture and toss to coat well. Transfer to the lined baking sheet. Repeat until all the balls are coated. Take the leftover confectioners’ sugar and transfer to a Tupperware container large enough to hold the rum balls in one layer. You can also store them in individual cupcake paper cups to hold them.
If the Tupperware container isn’t wide enough to hold all the rum balls, coat the base of the Tupperware with 1/4 cup of the confectioners’ sugar mixture. Line the rum balls in it. Top with a sheet of parchment paper and another 1/4 cup of the confectioners’ sugar mixture and lay the rum balls out. Repeat depending on the depth of the container and the number of balls. Store the rum balls in the refrigerator for up to 1 month in an airtight container. Rum balls are best eaten at room temperature (with warm brandy). Rum balls taste the strongest the day they’re made, but their taste smoothes out after a day of storage.
