Preheat oven to 150°C (300°F).
Mix together the pecans, salt, maple syrup and melted coconut oil. Spread out on a lined baking sheet and bake for 12-15 minutes until the maple syrup has coated the pecans.
Leave to cool for 10 minutes until set. Try not to eat them all!
Tip into the bowl of your food processor and process until finely ground. Scrape down the sides of the bowl and continue to process until a smooth nut butter forms. For pecans this takes around 5 minutes.
Transfer to a clean jar.
