Preheat the oven to 160C (140C fan forced).
Spread the tamari coated almonds in a single layer over a lined baking sheet.
Toast the nuts for approximately 10 - 15 minutes, stirring every 3-5 minutes. Stirring the nuts ensures they remain evenly coated with the tamari and allows them to roast evenly. Do keep an eye on them towards the end of the cooking time though to ensure they do not burn.
Cool the nuts for 10 minutes on the tray.
Transfer the slightly warm almonds to an airtight jar for storage.
