The first batch of pancakes she makes however, go in the bin.
"Not quite right, darlin'," she says in the kitchen of her fabulous West End home. "Just a wee bit over-cooked."
The entertainer's attention to detail, and determination to please is not, however, limited to her leek soup and pancakes.
The lady hasn't survived in 'the business' for 60 years simply because she turns out decent fare. No, she works hard at her content and her performance.
And today highlights that. As soon as the lunch is over it's down to the detail of her upcoming Tron Theatre show.
Dorothy is set to feature in her first ever Audience With . . . type evening, with yours truly asking the questions. And Dorothy wants to get every aspect of her life just right.
"I'm really looking forward to the evening," she says. "I'm glad you're going to be asking the questions. But we've got to get the balance right.
"We want to tell the stories about my life, but at the same time we've got to try and be awfy funny, darlin'.
"I don't want people coming out and not having had a right good laugh."
And get a few surprises along the way? Is she up for a few tricky questions being thrown her way?
"Oh yes I am," she says, grinning. "And that's what you journalists do."
Regardless of how 'tricky' the questions are, fans are in for a treat.
The special charity evening will begin with Dorothy performing her classic cleaner sketch.
And the show will feature her singing daughter Lisa and friends Margaret Woods and Lawrie Baxter.
However, Dorothy is a classic storyteller. And fans will wallow in the tales she has to tell.
"I'll be talking about my mother of course," she says smiling. "She was just so incredibly funny. And I'll be talking about schooldays growing up in Dennistoun."
She'll reference other famous entertainers to come out of Dennistoun such as Rikki Fulton, Lulu and Bill Paterson.
She will talk about her early days as a schoolgirl soprano, her teenage days spent cycling and meeting boys. And of course the dancin'.
"We were all looking for the man of our dreams," she says, smiling.
"And the young men we met were just that. For about a fortnight."
Dorothy will talk about her first job in C&A department store, working with a young Vera Weisfeld, and the move into showbiz, touring the country's small theatres and entering a world she couldn't have imagined.
"Working summer seasons in the likes of Rothesay was an absolute eye-opener," she says, grinning. "I'll have to talk about that."
Dorothy moved onto television and stardom in 1959 with the One O'Clock Gang, and found fame in sketch comedy.
But it was a gruelling experience, coming up with new comedy routines every day.
"There were some days I just didn't want to go on," she recalls. "The pressure just got too much."
However, Ms Paul grew to become one of the biggest names in entertainment in the country. But then came the difficult years.
She moved to Ireland with her husband, but when he died she had to bring up her two daughters.
Dorothy's life became a battle to survive. And one of the toughest battle grounds was the working men's clubs, during the Sixties and Seventies.
When club work was all to hard to find, Dorothy took in lodgers and sold insurance. She became a seamstress. She read the news on STV.
Now, Dorothy is at the age (74) where she can reflect on life, the hardest of times, but also the best of times.
"Comedy comes out of tragedy," she says. "And where you have drama you have the opportunity for a funny story. My life's certainly had enough drama in it."
The show will guarantee many funny moments. And even when Dorothy, who's working on the next volume of her life story, talks about her battle with the bottle, she'll reach for humour.
When she reveals how tough it has been for a woman to survive in the entertainment industry for 60 years, she'll do it with a wry smile on her face.
She'll talk about those in showbiz who've been fantastic to her her over the years.
BUT she'll also talk about the many times when she's been so wracked with nerves she contemplated going back to her old job at the Kraft Cheese Company.
"I will be a wee bit nervous on the night, because it will involve me baring my soul a bit," she says.
"But you'll be there to keep me right," she adds, grinning.
"We're going to have a lot of fun with this show, aren't we, darlin'?
"Now, do you think I should tell them the story about the Kirkcaldy Miner's Club. Or do you think it's too rude...?"
