Nimbu pani is a refreshing Indian limeade that checks every practical box for a Charlotte weeknight. All five ingredients are stocked at every major chain—lime juice, sugar, water, and mint are supermarket staples, and black salt (kala namak) is widely available at Food Lion, Harris Teeter, and Kroger in their international aisles, requiring no special trip. The five-minute time claim is honest and possibly conservative; this is genuinely just stirring. At roughly 40 cents per serving, it's one of the cheapest recipes you can make, driven only by the lime and mint. The drink doesn't reheat, but it's designed to be consumed immediately on a hot day, and a batch for two takes seconds to refresh if needed. The only minor drawback is that black salt is slightly more specialized than table salt, which might require a label-reading moment for first-time buyers, though it remains a standard grocery item.
