Pour the milk into a stainless steel saucepan (note: turmeric will stain anything white or lightly coloured so best to use a metal pan). Add 1 teaspoon of the turmeric spice mix and gently whisk together with a metal whisk. If using it, add the coconut oil and whisk through. Place on a medium heat until the mix starts to boil. Reduce the heat and allow to simmer at least 5-7 mins, or a little longer if you can, whisking intermittently. Just before it is ready, add maple syrup or honey to taste and whisk through. If you have a hand held milk foamer, you can also use this at the end to create a nice foamy layer on top of the latte. When ready remove from heat and pour into a mug. Enjoy!
