I want to know the answer to the following question:
Pork scratchings, pickled eggs and salted crisps are examples of what type of food?
All the background I'm provided with is that "Many pubs were drinking establishments, and little emphasis was placed on the serving of food, other than sandwiches and "bar snacks", such as pork scratchings, pickled eggs, salted crisps and peanuts which helped to increase beer sales.". Is that enough to answer the question?
