I threw an onion and 1a celery stalk in my food processer first and carmalized it. Once the sauce was made I peel a potato and left it whole in the sauce to absorb the acidity. I added sugar to it to add sweetness. I have to say I love my sauce. I use 4 types of seasoning not inlcuding salt pepper and a dash of red pepper. To each is own. I like a flavorfull sauce. I managed to get my picky fiance to eat it and he enjoyed it. I also read to cut acidity to add butter Good luck:).
