At Burren Balsamics we are committed to reducing food waste. We infuse our vinegars at low temperature which means the infused ingredients do not disintegrate during cooking, and can be further utilised to make delightful jams, chutneys and marmalades. Our Roast Onion Jam is made from ingredients in our Roast Onion Infused Balsamic Vinegar. Rich and mellow, stir into a gravy to add a rich flavour, great in sandwiches and of course with cheese. Ingredients: Onions, balsamic vinegar of Modena (concentrated grape must, grape vinegar), sugar.
