Preheat oven to 350°F
In a medium saucepan, stir together honey, granulated sugar, Irish whiskey and salt. Cook over medium heat for 3-4 minutes, or until sugar is dissolved and mixture comes to a slow boil.
Add walnut halves. Stir to coat. Simmer for 5 minutes, stirring, until syrup begins to bubble up and turn a light brown in color.
Remove from heat and drain liquid through a strainer.
Line a cookie sheet with parchment paper. Place coated walnuts onto parchment paper in a single layer, separating as much as possible.
Place in the oven and bake for 8-10 minutes (watch closely so they don't burn).
Remove from heat and allow to cool.
Once cooled, separate walnuts from each other and use to top salad, stir into yogurt or as a tasty snack.
