Been thinking about trying Grant Loaf again after gobbling up many slices of what tasted very like what I used to make in Connemara a couple of weeks ago.

Here's one of the many versions online (I've tightened it up a bit:

Add 1 ½ level tablespoons of dried yeast to 1 ½ rounded teaspoons of dark Barbados sugar (you can use honey, but I like burnt liquorice taste you get off molasses)
whisk in 1 ½ tablespoons of blood-heat water in a small bowl.
Leave yeast to activatee and foam, which takes 20-30 minutes. I found that placing the bowl in a larger one filled with warm water sped the whole process up.
Weigh out 1 ½ pounds of stone-ground wholemeal flour into a large bowl and mix in a teaspoon of salt. If you don’t have somewhere warm like an airing-cupboard, put the flour in an oven at the lowest temperature possible and let it warm through.
When the yeast is ready, make a well in the flour, pour in the frothy mixture and slowly pour in one pint of blood-heat water, mixing thoroughly with your hands. The dough should be quite sticky, though you may find you don’t need all the water.
Split the mixture between a large and a small greased loaf tin and allow the dough to rise for about 45 minutes (I put it back in the still-warm oven).
Bake for 40 minutes at 200°C.
