What simple addition to thinly sliced chambakka submerged in cool water is recommended to enhance its cooling property for afternoon consumption?

A pinch of sea salt and a squeeze of lime

The text details a specific preparation method intended to maximize the hydration and electrolyte benefits of the water apple, especially when consumed throughout the afternoon in hot weather. This preparation involves taking thinly sliced chambakka and submerging it in cool water for one hour. Crucially, to enhance its function as a natural alternative to electrolyte drinks, a pinch of sea salt and a squeeze of lime juice should be added. This combination capitalizes on the fruit's inherent high water ratio and mineral content, utilizing natural sources to aid in recovery from perspiration loss, subtly surpassing plain water in efficacy for rehydration after physical activity in intense heat.
