Thanks, Albert.
Although I normally wouldn't add any fruit, nuts, or sugar to a soda bread mix, and certainly not egg or butter. What the recipe in this video seems to be making is a cake, rather than a loaf of bread.
I wonder if the narrator has ever eaten real Irish soda bread. After all, she compares what her recipe would turn out to be like a large scone. That's not what Irish soda bread is.
I counted around ten separate ingredients in the video. The recipe in the one I linked to has just four: flour, salt, bread soda (bicarbonate of soda), and buttermilk (or soured milk) - okay, five if you count the two types of flour separately.
Buttermilk is readily available in Ireland. It's not sold much in England, so my sister normally adds a tablespoon of lemon juice to fresh milk instead (to replace the natural acidity in buttermilk, which is needed to release the carbon dioxide from the bicarbonate of soda, and so make the bread rise in the oven).
