Tea-flavored concentration from a teabag I was wondering if there was a way to make a concentrated flavoring from a teabag.  This probably isn't the best choice, but we have teabags readily available in our office breakroom, and I would like to occasionally add flavor to other hot or cold beverages.

Specifically, I sometimes make hot chocolate using steamed milk, and would like to make mint hot chocolate.  Alternatively, I'd like to make some concentrated chai from a chai tea bag and add it to steamed milk.
This may be an XY Problem: have you tried just dropping the teabag into the other hot liquid? For mint teabags, I suspect they'd brew just fine in Hot Chocolate to add a minty kick, and Starbucks makes a chai latte where they brew the chai and then add steamed milk after.
