Making a cup of chai for a friend at home can be quite fun, because you can use fresh ingredients, like fresh ginger, cinnamom sticks, cloves and green cardamom pods which you can break them with a mortar and pestle.
Making a mix for someone else can be a bit tricky. You will have to find a way to be able to grind all the spices into small chunk pieces. Of all spices ginger will be the hardest to find in dry form. If you have access to a local herbal shop or if you have a large Chinatown in your area, you could adventure to find a Chinese Herbal Pharmacy where you will definitely find all the spices.
If you have no access to any of the above, you could buy all the spices in powder form, mix them in equal parts (to make your life easier) and once you have your masala mix, mix it in equal parts with Assam CTC, which is the preferred type of tea for chai as it brews a rich and dark cup that goes very well with milk and sweetener.
Mix them well and you will have your own masala mix. it may not be as good as our Original Masala Chai, but your friend will sure appreciate the effort & love you put into making it from scratch
Hope this is helpful for you!
