Methods

1. In a small saucepan, bring 1 cup water and the slices of ginger (note - if you're using cow's milk here, don't add the ginger just yet, it'll cause the milk the curdle!) to a boil. 
2. Whilst the water is coming to a boil, measure out your spices into a small bowl.
3. Once the water is boiling, add spices and 1tsp sweetener and lower to a simmer for 3-4 minutes. Stir to combine if you're worried about the sweetener burning on the bottom. Your saucepan should smell divine right now.  
4. Add milk (room temp. if non-dairy, see note below if dairy!) and bring back to a boil. Now you're just bringing to a boil and simmering and bringing back to a boil (imagine a sine curve) until you've got a texture that you're happy with. Hell, you might be happy with it right away? I like a thicker, spicier chai - so I simmer and boil around three times - maybe 7-8 minutes total. 
5. If you like a more caffeinated chai - add your tea bags with the milk and let the tea boil with everything - this will get a little bitter but many folks crave that flavor! If you're like me and like a low caffeine chai, lower your heat and add the tea bag(s) for a minute right before you're ready to take it off heat. 
6. Strain using a fine mesh strainer and enjoy! I pour it into a saucer and sip like a cat because that's what my Nani taught me. 
7. The chai also keeps well in the fridge for a couple days and tastes great over ice, especially if you boil it down a bit more  on step 4 to account for the ice diluting it! 

Note on Dairy: 

My recipe works best for non-dairy milk. When fresh ginger is mixed with cow's milk at below 70 degrees celsius, the protease in the ginger causes the milk to curdle. So if you're using cow's milk - bring the milk to a boil in a separate saucepan and add it to the chai only once it's boiling hot. This will prevent the milk from curdling!
