Helpful tips
  • I use a food processor because the one I own has an exact slice system. If you rather use a mandolin, go for it.
  • My family made this in a 12 x 13 inch pan, but it's just myself and hubby so I half the recipe. If you want to double the recipe, the recipe has a slider at the top that allows you to adjust the servings. :)
