Who doesn't love a roast potato?

The carby treats have become a staple at Sunday lunch. Whether you're having beef, chicken, pork crackling or a nut roast, you'll need some roasties on the side.

So with that being said, it's probably a good idea to learn to cook them correctly! For that reason, we're drawing on a TikTok foodie for advice.

Marzia, who is known as Little Spice Jar online, told her followers that adding two simple ingredients can make all the difference.

She said: "The first tip is to use the right potato. You want something starchy like a Russet potato, which makes them extra crispy in the oven.

"The second thing you want to do is boil your potatoes in alkaline water and we do this by simply adding baking soda to the water while the potatoes are boiling – this breaks down the surface of the potatoes and gives them more nooks and crannies that brown up in the oven."

As well as adding baking soda to improve texture, Marzia recommends picking up some ghee or duck fat. These products have a 'higher smoking point', allowing them to "cook for a longer period of time at a higher temperature without burning".

For a final flourish, you can brush some garlic butter over the potatoes. This is an optional step, but can take the flavour of the tatties to the next level.

Viewers were very impressed with Marzia's tips – and took to the comments section to say so. One wrote: "I'm a chef and I can tell you this tutorial is perfect. Everything you've done 100 per cent [right]."

And another agreed, commenting: "I'm going to cry because it looks so good."
