Plant-based proteins are no longer a side dish in diets

milk needs to look like milk and taste like milk, whether it’s a fatty version, preferred by bakers, or a skimmed one, favoured by the health-conscious. And, for coffee-drinkers, it should ideally foam like the stuff from a cow. For years manufacturers have had trouble hacking this delicate imitation game. Rapidly rising revenues suggest that they are getting much better at it. In America alone, $2.6bn of plant-based milk was sold in 2021, up from $2bn in 2018.
