A Bit Of Onion Jam Goes With Everything

Onion jam is a sweet and sour jelly preserve that you’ll find yourself using in so many different ways. It marries well with most meats, with brie and crackers, in quiches, on sandwiches, on sausages, on hotdogs and of course slathered onto hamburgers. Your family will love having this blobbed on top of just about anything and you’ll make very good friends if you share a bottle or two. When it gets nearer to special occasions, make double the quantity and store in glass jars for quick pantry gifts that won’t disappoint.
