I will be visiting family in London for Xmas. I want to make them US-style stuffing which uses much larger breadcrumbs than what is used for the UK-style stuffing I remember from my childhood. In the US you can buy these large breadcrumbs, which are essentially dried diced chunks of bread, in bags any supermarket. Are they also commonly available in UK supermarkets? Or should I expect to make my own using old bread? Thanks in advance for any feedback!
