In a large bowl, combine the finely crushed vanilla wafers, ground nuts, sifted powdered sugar, and a pinch of salt.

In a separate small bowl, whisk together the tequila, orange liqueur, fresh lime juice, lime zest, and corn syrup until smooth.

Pour the wet ingredients over the dry mixture. Mix and knead with your hands until a cohesive dough forms. If it's too dry, add a splash of tequila; if too wet, add more powdered sugar.

Cover the bowl with plastic wrap and chill in the refrigerator for at least 30 minutes to firm up.

Once chilled, scoop 1-tablespoon portions of the dough and roll them into smooth balls between your palms.

Roll each ball generously in the coarse sugar (mixed with a little extra lime zest if desired) until fully coated.

Place the coated balls on a parchment-lined baking sheet and refrigerate in an airtight container for at least 24 hours before serving to let the flavors meld.
