I actually make it at home. It's really easy.

Fresh brewed tea ingredients:

Thai Iced Tea Traditional Restaurant Style,16 oz (1LB.) https://www.amazon.com/dp/B000UPNK9S/ref=cm_sw_r_apan_glt_fabc_E71PQJZJY21SN309K6MP?_encoding=UTF8&psc=1

Whipping cream (or dairy/non-dairy of your choice) Sweetened to taste with sugar, honey, or syrup I sometimes put vanilla extract, but usually no sweetener personally

Instant tea for slightly less work:

Unknown DEDE Instant Thai Tea Drink with and Sugar 12 Pockets, cream, 14.76 Ounce https://www.amazon.com/dp/B000EEG952/ref=cm_sw_r_apan_glt_fabc_BBQPM38PM0J5CX3GQ8AN?_encoding=UTF8&psc=1

Boba: E-Fa Brand Premium Grade Black Tapioca Pearls (6.6 lb) [Bubble Tea] https://www.amazon.com/dp/B000CR06BO/ref=cm_sw_r_apan_glt_fabc_B33AVD4P44N3962SR1CC?_encoding=UTF8&psc=1

It's important to me to get this brand because it's so simple to make them taste good. All I do it get a pan with boiling water and drop a couple handfuls of boba in. Let it boil for 5 minutes, drain excess water, and you have great boba every time.

I'm interested in making this, but I have no idea what Thai Tea is. Can anyone point me to what sort of instant mix you would want to use? Is this the sort of thing Jan is talking about?
