making boxty

A little treat for lunch today... unfortunately they didn't turn out the way I remembered them! I had a recipe, but I never wrote it down! I was making them quite regularly for my husband in the early days of our relationship, trying to impress him! I'm still fairly sure it was 5 potatoes, 1tsp of baking soda, a pinch of salt, and then flour and milk, but their quantities i can't remember! Today I went with 3 tblsp of flour and an unmeasured amount of milk, and they turned out a little too soft. But I'm not sure now was it the temperature (too hot, not cooking them long enough) or did I maybe put in too much milk, or maybe the amount of flour was all wrong too? I don't know!

Does anybody have an all-raw-potatoe boxty recipe? This one I got from Peter's granny, who sadly passed away last year. It was one of those 'a few of these - a bit of that' recipes grannies like to give out, because they've spent some 60 years cooking it, there's just no measuring necessary!
