Boxty is a traditional potato dish, celebrated in the rhyme.
Boxty on the griddle, boxty in the pan, If you can't make boxty, you'll never get your man
Grate the raw potatoes into a bowl. Turn out onto a cloth and wring, catching the liquid. This will separate into a clear fluid with starch at the bottom. Pour off the fluid and scrape out the starch and mix with the grated and mashed potatoes. Sieve the dry ingredients and mix in along with the melted butter. Add a little milk if necessary to make a pliable dough. Knead lightly on a floured surface. Divide into four and form large, flat cakes. Mark each into quarters but do not cut right through, and bake on a griddle or in a heavy pan.
If liked, more milk and an egg can be added to make a batter which can be fried in bacon fat like drop scones.
