Mmm, I like limeade. Squeeze 1 whole lime into a bucket, add anywhere from 0 to 2tsp of sugar, fill to the brim with water.
I like it to be flavored with lime, not so much that I pucker. Same with lemonade, ’though limes can be sweet’n’sour (like grapefruit), whereas lemons are usually just bitter, so I need at least 2tsp of sugar with lemonade.
Hey, I cut sody-pop half’n’half with water, else it’s like drinking kanar, sweet and syrupy, yecch.
So it ain’t cheap, as 4/1buk for limes makes, what?, a quart?, per lime, but it’s good, and natural.
In extreme desperation, I can do ReaLemon or if available ReaLime, but… desperation.
In hot tea, I like slices of lemon, but again, in desperation, a splash of ReaLemon will pass.
Æons ago, if going away somewhere and would be staying in a hotel, a ziplock baggie with tea-mix (Nestea?) would beat plain water. Not by much, but doable.
If you can get to Chinatown or at least an ethnic part of town, pick up some “gunpowder” green tea. Coupla bux for a box, drop a half-spoon of it into a mug of hot water, watch the “peppercorns” of tea unfurl into “spinach” at the bottom of the mug. And enjoy with honey. Or straight.
Oh, let it settle undisturbed, unless you want a mouthful of fines to make you near-puke from unexpected bitterness. Best to use a traditional teapot to decant as needed, and leave the yick at the bottom.
