Lord Sugar summons the candidates to an 18th-century tidal mill in the heart of London's East End. For the third task, they manufacture and sell upmarket doughnuts to both a corporate client and the public. One half of each group must fathom out flavours, while the others set off to bag a bespoke order from the corporate world. For one team, a decision to add spice turns up the heat, while on the other, toying with teabags sees tension brewing. Sugar then decides which candidate is past their sell-by date in the boardroom.
