Farro, a variety of wheat grain, has a hearty, slightly chewy texture. It provides a nutty base for our winter root vegetables, sweetened with pear and a little sorghum syrup. Sorghum syrup – an old-time sweetener similar to molasses – is very thick, so we diluted our ingredient here for ease of use. (If you had to wait for full-strength syrup to pour from the bottle, you’d be in your kitchen all night.)
