This infusion is popular in Iraq; it is made by seeding the noomi Basra or dried limes and simmering the peels in water for 15 to 30 minutes; drain and sweeten. Apparently it helps with tummy aches and digestive issues.
I did not have the patience of seeding the limes, I simply poked each in 3 places, dumped them in lots of water and simmered them for 15 minutes. I used 2 limes for a quart of water. I added sugar (or honey) to the infusion as it tends to taste sour.
