The secret in this cup of black tea is a few Lemon Verbena leaves. They are steeping in the brewed black tea, loose or bagged, giving it a lemony flavor without needing any citrus fruit.
People ask me how many Lemon Verbena leaves to use per cup, and I say, "That depends on how much lemon flavor you like."
I suggest starting with three whole leaves of Lemon Verbena in an 8 - 12 oz cup of tea. Yes, that's a big teacup. But anyone who buys tea at coffee shops or convenience stores is used to even larger cups!
