It is cheaper to roast your own nuts. So I have my owner buy unsalted nuts, cashews or walnuts, almonds, pine nuts. Use a bland oil like grape seed or safflower oil, or this time I used maple syrup so the nut had a sweet taste to it.
Preheat oven to 350 F
Take large baking pan with sides, line with parchment paper or use a baking liner. In a large bowl take 1 1/2 kg of nuts and mix it with your liquid, so in the case I used maple syrup, 1/2 cup, making sure that all the nuts get covered. If you like your nuts spicy add, a 1 tbsp. of hot spice or other types of spices that would go nice with the flavour of the nut depending on what you like. If I am adding a spice then I use oil vs maple syrup as maple syrup will sweeten your nut.
Then spread out onto baking sheet and put into oven. Bake for 5 minutes then take out and stir, put back in and bake for another 5 minutes, then turn oven off and let the nuts cool in oven however, make sure you stir from time to time. The nuts should brown up as they cool down.
