This week's episodes see Tracy embark on a relationship with Ryan Connor (Sol Heras) after they begin working together at Dev Alahan's kebab shop.
While Ryan is delighted with the new romance, he is unaware that Tracy's main aim is to annoy Michelle and Steve.
Discussing her initial reaction to the story, Ford told itv.com: "I was quite nervous, actually. I'm 34 and obviously he's a lot younger, so I felt slightly out of my comfort zone. When we did the first kissing scene, we were both really nervous, however now we're absolutely fine as we've done it a hundred times!
"What is great about this story is that it's quite funny and I was looking forward to doing something comedic rather than dark, so it's a laugh."
Meanwhile, asked why Tracy wants Steve so much, the actress replied: "I think it's that old classic of wanting what you can't have. I don't know how she'd feel if she ever got him, whether she'd be bored after a year or two.
"I think it's because she's never truly had him that she's so anxious to have him in her life. She can't bear the fact that he doesn't fancy her and he doesn't love her."
Coronation Street kicks off the Tracy and Ryan story tonight (September 3) at 7.30pm on ITV1.
