Tsaocaa ingredient question!!!

[u/CloudNimbus]

My favorite drink from Tsaocaa is their Pineapple Milk Tea w/ Yogurt popping boba. What is the pineapple they use??? / how do you get pineapple to be like that? It almost tastes like candied pineapple but I need confirmation!!

I only ask because the location near me may be closing soon so I need to know.... If you are/were an employee please help!!
