It takes a lot of balm to make tea, though doesn't it Chary? I used to grow lemon verbena and use it for tea, but I chose it because my space was limited. I didn't have the space to grow enough lemon balm to make a strong tea.
I'd use it in anything that could use lemon. In salads, fish, chicken, soups (although I wouldn't add it til the end), potatoes...in sliced strawberries with a bit of sugar...mixed with regular black tea if you use lose tea.
