Turn oven to 200 degrees for a fan oven or 220 for a conventional oven.
Crumble the yeast into a container. Spoon in the treacle (leave the spoon in). Add a 1/4 pint of lukewarm water. The water should be above body temperature (if it’s too hot you will kill the yeast). Leave aside for ten minutes, while the yeast is activated by the warmth and feeds off the treacle.
Heat the Black Rock Stout on the hob, being careful not to boil it. Should be above lukewarm.
While this is heating, you can measure out the flour and salt into a large bowl. Mix with your hand, making a hole in the center.After ten or so minutes the yeast mixture should be frothing at the top. Now stir this mixture vigorously and pour into the hole in the center of the flour. Pour the Black Rock Stout into bowl.
Now it’s time to get sticky. Using your hand in a circular motion from the center, mix the flour with the liquid. Mix well being sure not to leave any dry flour. The mixture should be like wet cement. Pour into the buttered and floured loaf tin.Sprinkle with seasame seeds (a mixture of black and white seasame seeds looks great). Fennel seeds work well too.
Allow to rise in the heat of the kitchen for five to ten minutes, ’til the dough is nearly level with the lid of the tin.
Place in the oven for forty minutes. Cook for a further five minutes out of the tin.
