Hi all - preparing a bolognese to cook tomorrow, have sauteed the onions and garlic and browned the mince (it's not 100% cooked through though, just browned). Can I now add the rest of the ingredients and bung in the fridge overnight, then put on to cook tomorrow? Somehow the thought of partially cooked beef simmering for hours is making me think "food poisoning". Am I missing something??! Thanks
