The Griffin, in Milk Street, is hosting the contest – nicknamed the Eggs Factor – to find the ultimate pickled egg.
The idea began as bit of a joke, after pub staff realised customers were getting through more than 25 pickled eggs a week.
So manager Charlie Thomas decided to run a competition to raise money for Dorothy House Hospice.
She said: "We get through a jar a week, which is quite a lot of eggs and as they are so popular in the pub, we thought it would be a great idea to get people to make their ultimate egg."
Anyone can enter the competition, which will be held on Easter Sunday, April 12, at the grand Egg-Off.
Only authentic eggs with genuine ingredients will be eligible to enter, and they will be judged on their taste, overall appearance and labelling or packaging.
Prizes include a gold leaf egg gilt and T-shirts.
There will be a panel of celebrity judges, which have yet to be announced.
It costs £2 to enter and people can put forward as many eggs as they like.
Anyone interested in taking part can call Miss Thomas on 01373 467766.
