Milder and sweeter than their white cousins, the red onions are slowly cooked down with black treacle, balsamic vinegar and Carwright & Butler's blend of spices into a rich marmalade-style chutney. It works particularly well with a sharp cheddar or creamy goats' cheese. While a dollop stirred in your beef gravy will be a revelation. Like all their chutneys and preserves it comes in their signature clip-lid jar, that is eminently practical as a re-useable airtight storage jar.
