Cut a lemon in half and use a simple lemon squeezer to collect the juice.
Spoon ¼ teaspoon of powdered turmeric, ¼ teaspoon of powdered ginger and a pinch of cayenne pepper into a small glass.
Pour the lemon juice over the spices, stir to suspend the powder in the liquid and drink immediately.
While this is the easiest shot, it’s not the tastiest. If you’re willing to put a little more effort in, there are ways to make it more pleasant.
