Raw cashews lack the structural starches found in grains, meaning their creamy consistency relies entirely on the mechanical breakdown of fat and protein cells suspended in liquid. When you soak raw cashews overnight, water penetrates the cell walls through osmosis, softening the dense kernel so the blades of a food processor can shear the material into a microscopic emulsion rather than a gritty paste. Without that hydration window, the machine simply shatters the nut fragments into hard granules that no amount of blending will fix.
Creating a spreadable dairy alternative requires managing friction and moisture simultaneously. As the processor runs, the friction generates heat that can prematurely coagulate the proteins, turning the mixture pasty or gummy. Adding the water gradually allows the fats released from the cashews to form a stable water-in-oil emulsion. If the motor struggles, add water strictly by the teaspoon; excess liquid breaks the emulsion, resulting in a thin sauce rather than a firm spread.
