Of late, I have become addicted to limes. In the morning, I squeeze a wedge of lime into my cup of hot tea (currently Darjeeling). At dinnertime, I mix the juice of half a small lime with a glass of tea remaining in the pot since morning, and add a packet of non-caloric Splenda to sweeten it.
Sometimes, when I think I am drinking too much tea (as I am wont to do), I just replace the cold tea with water, sometimes adding a dash of tequila, particularly when it is hot.
Typically, I buy limes by the bag. The unit price at the market is ridiculously high, and I have no difficulty finishing a bag of twenty or so limes within a few days.
What about lemons? I used to use lemons the way I use limes, but I have come to prefer the flavor of limes. During my travels in Mexico and Central America, I have rarely seen lemons at all. I presume that they grow there, but the locals, like me, probably prefer the taste of limes.
