Cover and refrigerate for an hour. Lightly grease the edge of a knife and cut into squares or bars. Store in the refrigerator between parchment paper strips.
If you don't have any of the nuts, substitute that with the ones you have.
For dates or apricots, you can substitute with raisins, cranberries, figs or any soft dry fruits.
To get a smooth edge while cutting, grease the knife with oil or clarified butter.
