In the early 1940s, during World War II, Howell was on radio with the BBC Home Service, contributing Welsh-language content on diet and for schoolchildren.[5][6][7]
In the 1950s Howell was a program assistant in early radio and television productions based in Bangor,[8][9] including Noson Lawen (A Merry Evening).[10] In 1952 and 1954 she gave the "shopping report" on the BBC radio program Woman's Hour.[11][12] In 1952, she gave a recipe for Aberffrauw cakes (a shortbread variety associated with Anglesey) on Welsh Diary on the BBC's General Overseas Service, when Welsh speakers abroad requested recipes on the program.[13] In 1954, she hosted a special Welsh-themed edition of the BBC television program Leisure and Pleasure.[14] She appeared in a 1958 trial weekly series, Awyr Iach (Open Air) with Ron Saunders.[15]
Howell became well known as the presenter on the TWW programme Amser Te (Tea Time), the network's long-running[16] weekly Welsh-language afternoon program for women viewers, beginning in 1958.[15] The show featured recipes, interviews, competitions, musical guests,[17] live and filmed segments; "Howell's homely style of presenting endeared the audience to her."[18] The program's baking segments were popular enough to publish Tea Time Recipes, a cookbook of the recipes featured on the show in 1962,[19] and a sequel, Tea Time Round the World.[20]
Howell was also a justice of the peace.[1] In 1949 she became the first chair of the Welsh Counties Committee of the Women's Institute.[21] In 1954 she participated in the opening ceremonies of the National Eisteddfod, on behalf of the Women's Institute.[22]
