Last April, Quay took their famous snow egg off the menu. A bold move for a three hat restaurant that's been capitalising on that signature dessert since 2009. In 2010, chef Peter Gilmore's orb of vanilla ice cream and poached meringue coated in a toffee crisp and bedded on a seasonal fruit granita, made its debut on national television.

Four million viewers tuned into the MasterChef finale to watch contestants try their hand at this notoriously difficult-to-make dessert and since then they sold more than 500,000. Imagine the poor bookings receptionist wrangling the thousands of calls around whether or not it could be ordered without the rest of the menu (no) or whether it could be taken away (certainly not). When Gilmore decided to take the snow egg off the menu after a decade, he pretty much broke the internet.

So. Is a signature dish is a help or a hindrance when it comes to running a successful restaurant business? Good Food senior critic and Good Food Guide panel member Terry Durack says signature dishes will never die because restaurants need them as part of their brand. "They give their identity a consistent visual and a consistent voice. They stand for something."

He also argues that the dish gives a diner something to come back for - it becomes a status symbol, something you want to show your friends, colleagues, loved ones. So perhaps, in a way, it's a restaurant's responsibility to keep those popular dishes on the menu. They become a part of a larger conversation, more than a sum of the restaurant's parts and a chef's ego.

A waiter commented during a recent visit to two-hat restaurant Tetsuya's, that there had been a public outcry when they'd attempted to take the famous confit ocean trout, which has been on the menu at his Kent Street address since 1992, off the carte. The gently poached lobe of Petuna ocean trout with its konbu crust lolling over matchsticks of green apple might well be the most photographed trout dish in Australia - possibly the world.

Whether it's a delicate dessert, a perfectly poached piece of fish, or a showstopping piece of meat, there's the impression chefs do feel a little hoist by their own batard. Clayton Wells, head chef of Automata and A1 Canteen never expected his version of a muffaletta - a party of cured meats, cheeses and pickles - to be quite the runaway success it became. "I didn't think everyone would come and sit down here and be eating a sandwich," says Wells. "Which is not bad either. But it's quite a big thing." To this day, that sandwich is plastered all over Instagram. An affordable status symbol for the upwardly mobile.

Can you run a restaurant in 2019 without a big deal piece of protein? Without that show stopping steak, that duck for two, the luxury rare breed pork chop? A show stopping sandwich?

What about running a restaurant in 2019 without a big deal piece of protein? Without that show stopping steak, that duck for two, the luxury rare breed pork chop? "I think you could run it," says Lennox Hastie, head chef of Surry Hills wood-fired restaurant, Firedoor, "I don't necessarily think you can start it."

His 200-day-aged $200 rib eye steak has become a thing of legend in Aussie dining circles. And while the expectation around that is weighty, without it he may not also be able to sell some of the other dishes that excite him. It's a little like the blockbuster film that bankrolls a director's passion projects. "Chefs like to complain about having a signature dish they can't take off their menu," says Durack, "but they don't mean it. It's money in the bank."

Joy
Having cooked with heavyweights (Urbane, Sepia, Automata), Tim and Sarah Scott decided to do their own thing.
