One of my favourite products to use is Agave Necatar. You can buy this from any good health food store.
A good squirt of Agave nectar to coat pecans
1 tablespoon of brown sugar
1 teaspoon of ground French Perfume salt
A good grind of Pepper. I used Chai Shiraz Smoked Peppercorns
Mix well and place in a single layer on a line baking tray.
Bake for 10 mins then turn pecans, return to oven for a further 5 mins to allow caramalisation to occur.
Cool and enjoy
