Wheat Milk

Wheat is the most widely grown crop on earth, first domesticated in the Fertile Crescent around 10,000 years ago and now covering more farmland than any other plant. Oddly, it's almost the only great grain never to have won a place in the milk aisle. Partly that's gluten (the protein that makes wheat magnificent for bread rules its milk out for coeliacs), and partly oats and rice simply got there first. Traditional wheat-based drinks do exist, from Turkey's fermented boza to horchata's many cousins, and food researchers keep poking at wheat as a milk base. Made at home, it's mild, creamy and faintly bready. For now, though, wheat milk is a shelf waiting to be filled.
