Those lend cow’s milk its colour, texture, and talent to resist prime warmth, the latter of which is essential to fending off curdling when added to espresso or stovetop foods.

Minerals, plant-based fat, and a small amount of sugar flip the proteins right into a cow (and lactose) loose competitor to what some now imagine to be an old-fashioned product.
