Showcasing the recipe on Today Show in the US, Missy explains that the the key ingredients are fettuccine, parmesan and - wait for it - buffalo butter.
And while buffalo mozzarella is available in many good delis and some supermarkets, buffalo butter is a little harder to come by - leading some to cry foul.
Said one critic: ‘The whole point of three ingredients is that it’s easy - you can go to the store and buy everything you need in one hit. Or better still, it’s in your fridge or pantry at home. This is insane.’
Commented another: ‘Oh great, let me just pop down to 7-Eleven and pick up some buffalo butter.’ And one more said, ‘Where the hell am I supposed to buy buffalo butter?! Aren’t 3-ingredient recipes supposed to be easy?’
However many fans hit back to comment that buffalo ingredients are available in more boutique stores - and it’s worth the effort. ‘That’s what makes it an amazing dish - it’s worth finding!’ said one Missy Higgins supporter. Added another: ‘It’s called fine dining - you should try it sometime!’
Ouch! To get Missy’s recipe head here!
