Lukewarm water
Description
Warm water is water at a temperature of about 25–35°C, clear and colorless, devoid of odor and distinct taste; it feels pleasantly neutral, neither cold nor hot, which affects the comfort of use and subtle extraction of flavors. As an ingredient, it does not contribute calories, mainly providing H2O and trace amounts of minerals depending on the source; it supports hydration, thermoregulation, digestion, and nutrient absorption, and by contributing to the proper course of enzymatic processes, it is beneficial for metabolism. In the kitchen, warm water is indispensable for activating yeast, preparing starters, gently brewing teas and herbs, soaking nuts, or dissolving gelatin, as it does not damage protein structures or cause thermal shock. It is best stored fresh, filtered, and covered in a cool place; use within a day at room temperature or store in the refrigerator for a maximum of 48–72 hours, avoiding repeated heating and contamination.
