sparkling water

Sparkling water is water that has been carbonated through the injection of carbon dioxide (CO₂) gas under pressure, creating dissolved carbonic acid and characteristic effervescence. It may be naturally carbonated (sourced from mineral springs where CO₂ occurs naturally) or artificially carbonated in a controlled manufacturing process. Sparkling water differs from mineral water in that it contains no added minerals or salts, though some commercial brands may include trace minerals depending on their source water. The carbonation level varies by brand and product type, ranging from lightly effervescent to intensely bubbly.

Sparkling water functions primarily as a beverage, though it serves important roles in cooking and food preparation. In the kitchen, it is used to create light, airy batters for tempura and other battered preparations, to deglaze pans and dissolve fond, and as a non-alcoholic component in cocktails and mocktails. It is also employed in gelatin-based desserts and some baked goods to achieve lift. As a table beverage, it serves as a palate cleanser between courses and is commonly consumed on its own or as a mixer with spirits, fruit juices, or syrups. Its neutral pH and lack of added sugars (in unflavored varieties) make it a versatile culinary tool.
