We’ve been lucky enough to have strawberries, raspberries, blackberries and now these pickling onions from Martin Soble’s gorgeous Whitethorn Farm in the Herefordshire hills. Martin likes to do things the old-fashioned way, even if they take more time or offer lower yields. “Flavour and quality are what’s important,” he says. That’s why he selects traditional varieties and lets the sun and soil do the rest of the work.
