The closing date for nominations is May 25.
The ACE Robyns Award was launched in 2016 to recognise up and coming talent in the foodservice business, inspired by Robyn Jones, joint-founder of CH&Co, who died in 2015.
Entry requirements and the nomination form can be downloaded from the ACE website.
Laura Amos, catering manager for Ampersand at Holyrood House in Edinburgh, won the award last year. She said: “The exposure has been amazing. We are restricted with social media at the palace, and have to do everything through the Royal Collection marketing team, so I set up a personal Twitter account when I knew I was shortlisted.
"When it was announced it went insane! People have been following me and adding me from other catering and hospitality businesses. It was a real buzz.”
