Pulse soaking is the controlled hydration of dry pulses in water prior to cooking, blanching or further processing, shortening cook time, improving texture and reducing the oligosaccharide content associated with digestive discomfort.
In trade practice
In industrial processing, soaking is carried out in tanks with controlled water temperature and duration; water quality, including hardness and pH, affects hydration rate and can influence the texture of the finished product. Food-service buyers may specify soaking time and water-to-pulse ratio in cooking protocols, as these directly affect yield and eating quality. A common mistake in specification writing is omitting soaking instructions, which leads to inconsistent results across different kitchens or production sites. Where pulses are sold for retail with cooking guidance, soaking instructions on pack must align with the tested protocol.
In a specification
A cooking specification or processing protocol should state the recommended soaking duration, water temperature and water-to-pulse ratio, and note whether soaking water should be discarded before cooking.
