The Cock Tavern in Hackney changed my life when I started working there 10 years ago. The pub was heavily focused on craft beers, of which I had little knowledge or interest. So I focused all my attention on the jar of pickled eggs. I sold them all within a few days, ordered more, sold out again, and so on. Sales went through the roof and we invested in eight different flavours. We sold so many that I ended up winning a pickled egg award from the supplier – we’d sold more than anywhere else in the country.
