HG Walter is one of London's favourite butchers. Here, the team shares their suggestions for sourcing the best ingredients:
"As with anything you cook, the end result will be hugely affected by the quality of your ingredients. Seeing as the egg is the star of the show here, it is so important to choose the best available. We use Free Range Burford Browns which give a delicious, rich orange yolk.
"The sausage meat to wrap your egg in is just as important. Go to your local butcher who should have a good quality free-range pork sausage meat available. We always use our plain pork sausage meat but different flavours work well too.
"Steer clear of the bright orange coloured breadcrumbs that you find in the supermarkets. The best breadcrumbs are homemade but if you have to buy them in, opt for a good-quality brand such as panko."
