Lemon Nana

This is a very refreshing drink from Jordan. I read about it in the travel book and did not see it anywhere. One of the first days of our round trip, we´ve been to an Oasis and had lunch there. The offered drinks were the usual softdrinks.
I asked a waiter for Lemon Nana, he look astonished, then said ok and went back into the kitchen. It took a while and he came back with a glass full of minty light yellowish liquid. I took a sip and was hooked. It became the signature drink of our group during our tour through Jordan.
It is now three years ago, that I travel there, but when summer comes here and the pots of mint on my balcony are in full swing, I remember it and prepare it often.
