A classic Mid-West American drink.
If you want a fancy presentation, you can put this in one of those loose-bottomed pie / quiche pans whose bottom pops out. Otherwise, use whatever type of pie dish you have to hand, preferably a 9 inch / 23cm round pie tin.
A lime squeezer (aka citrus press) is a squeeze mechanism that you work in one hand by pressing firmly in on two handles. You place half a lime in the squeezer end, which has drain ends in it for the juice to flow out, while holding seeds and pulp back.
You can make this up to a day ahead, stored in the refrigerator in a sealed jar or container.
