There's little MasterChef judges Matt Preston and Gary Mehigan haven't tasted or experimented with in the way of food.

But it seems that the duo are fed up with some culinary trends.

The pair have revealed the list of foods that are 'banned' in the Masterchef kitchen this year.

Parfaits, deconstructions and smears: Matt Preston and Gary Mehigan reveal the 'banned list' of food forbidden in the MasterChef kitchen

'Smears — banished, deconstructions — don't go there, spheres — outlawed, crumbs — fed up with them,' they said during an interview with Confidential.

'Parfait is also forbidden in 2018, as is 'over-reliance on the blast chiller.'

The chefs explained that with trends constantly evolving, some foods reappear after being ruled out in previous years.

'The weird thing is that dust (powdered food) has reappeared and we're like 'actually that's not that bad, it actually tastes like something', so we've taken that off the banned list for a couple of weeks,' Matt remarked.

The duo also confirmed that garnishes are a strict 'no', stating that if you can't eat it then it doesn't belong on the plate.
