I have dabbled with almost every ingredient I can think of in varying amount to get my Bolognese to taste similar to a restaurant made Bolognese in the italian alps.
Including: Pepper Sugar Salt Tomatos and tomato puree, tinned and chopped tomatos garlic lea & perrins / Worcester sauce Onions & onion gravy granules different meats, pork, beef and veal Herbs Basil, greek basil, thyme and oregano red wine and most recently balsamic vinegar
These all get close and do make a nice Bolognese. However the secret ingredient is still missing!
