Lay pecans out on a baking sheet and toast in the oven for 7-10 minutes at 350°F / 180 °C until fragrant.
2 cups Pecans
Add the cooled pecans and salt to the food processor/blender and process on high speed, it will slowly go from chopped pecans to a chunky paste as the natural oils start to release.
Add the salt and keep processing until it is smooth and the consistency you want (process less for a chunky pecan butter). Make sure you regularly pause to scrape down the sides of the bowl.
¼ teaspoon Salt
Once the desired consistency is reached, add the sugar and blitz for another few seconds, just until combined.
1 tablespoon Icing Sugar
Pour into a glass jar or airtight container.
Notes
Toasting the pecans is an important step, not just for flavor but because it helps to release the natural oils in the nuts which will allow them to blend up into a nut butter. If you skip the toasting, you may not get the desired results. It is also important to use a food processor or blender which is powerful enough to make nut butters - check your model to see if it has the strength to do this or you risk burning the motor out.
