Toast tiger nuts in a skillet on the stove for 3-5 minutes, stirring continuously. You don’t need to add any oil. (Do this on medium-low heat.) They can burn easily, so keep a close watch.
When the tiger nuts start to turn lightly golden, transfer them to a medium mixing bowl. Set aside.
Make pecan butter by putting pecans in the food processor. Pulse until you get a thick paste.
Melt the coconut oil. Then add the melted coconut oil, salt, and monk fruit powder to the pecan butter. Pulse until ingredients are mixed. Scrape down the sides several times during this process to get a smooth, even blend. (You can also use a blender if you don’t have a food processor.)
Transfer the pecan butter/coconut oil mixture into the bowl with the tiger nuts and stir until tiger nuts are well coated.
For best results, use a mini scoop to create the clusters. Pack the mixture tightly into the scoop. Then release the contents of the scoop onto a cookie sheet or other flat pan that will fit in your freezer. (Pyrex baking dishes with unbleached parchment paper also work really well.) If your mixture is too crumbly and doesn't hold together, you can mix in more coconut oil. Just add extra in very slowly so it doesn't get too runny. OPTION: If you can't get the mixture to hold a ball shape, you can spread it out into a layer. When frozen, you can use a knife to break up the pieces into a pecan "bark." It tastes equally delicious.
Put the tray of clusters into the freezer for about an hour. Gently remove the clusters and enjoy!
Store leftovers in enclosed storage containers. Store in your freezer or refrigerator and eat cold.
