We had some fantastic “English Cheddar with Caramelized Onions” from Trader Joe's today. It looked like the caramelized onions were added during the milling step. It had a patchy (wish I would have taken a picture before we ate it) look to it. The ingredients list milk, salt, rennet, cultures, onions, granulated sugar, Muscavada sugar pectin, Balsamic vinegar, lemon, and citric acid. By the look of the ingredients’ I’m assuming some kind of onion jelly was added to the cheese. Does that seem right?
