"I like to parboil them just a bit to begin with, and then toss them in something like semolina, or scratch them so you get them all crispy," she said during an episode of Britain’s Best Home Cook. "Then put them in a really hot pan with goose fat."

"My recipe has changed over the years – flours have become more refined and I find I get the best rise adding more eggs and omitting a little milk," she said. "If you only have full-fat milk, replace a quarter of the milk with water."

For those with a sweet tooth, Mary has previously unveiled that baking dessert can be much simpler than people assume. Sharing her five-minute Victoria Sponge cake hack, she wrote for The Telegraph: "I no longer prepare a Victoria sandwich with the traditional creaming and folding methods, as this all-in-one method gives excellent results every time. All that creaming of butter and sugar. I never seem to have the butter soft enough. And then the tins have to be lined and everything has to be just so."

Instead, Mary uses baking spread, which she simply places in a large mixing bowl with sugar, eggs, flour and baking powder until it's smooth. Her all-in-one method can be used with cakes, tea breads and biscuits – it's that simple!
