Cooking with Alkali
Researcher: Alec Borsook Overview Alkali cooking techniques are largely underexplored in contemporary kitchens. This post is a basic overview of what alkalis are, what they do, and how they can be useful.A notable fact is that calcium hydroxide (Ca(OH)2), one common alkali, can be made quite easily in kitchens by burning eggshells, whose calcium carbonate is then converted into calcium oxide (quicklime, CaO), which can be ‘slaked’ with water to become calcium hydroxide. Acidity comes in many delicious forms. Much of the research performed here at the Lab concerns our unending search for them, from our exploration of sour wild things to our investigations of the possibilities of lactic and acetic acid fermentations. Acids can balance flavours, providing brightness and cutting through richness, or they can make you pucker your lips in a delight bordering on pain. But what about their chemical opposites, the alkalis? In continuation of some previous … Read more
