Baker's highest profile role was as Nellie Pledge in the Granada Television comedy series "Nearest and Dearest" (1968–73). Playing her brother Eli was the comedian Jimmy Jewel and the series was centred on their characters' love-hate relationship as they tried to run their small family business, "Pledge's Purer Pickles". As they bickered onscreen and traded insults such as "knocked-kneed knackered old nosebag" and "big girl's blouse", the insults continued off-screen as the two performers disliked each other intensely. A film version of the series was made by Hammer Films in 1972 (the same year she was a subject of "This Is Your Life" when she was surprised by Eamonn Andrews). Later in the series, Baker began having trouble remembering her lines and had to rely on cue cards and prompts from her co star Madge Hindle, who would whisper her next line to her.
