A creamy blue cow’s-milk cheese from Tipperary, soft enough to spread on soda bread. Jane and Louis Grubb began making it in 1984; it was Ireland’s first farmhouse blue and it led the country’s artisan cheese revival.
Growing Penicillium roqueforti through a cheese needs the culture, needle piercing at the right moment and a ripening room held at controlled temperature and humidity for months.
What goes into it
- milk from the farm’s own herd
- Penicillium roqueforti
- rennet
- salt
How it is made
The milk is set with rennet and inoculated with blue mould spores, the curd drained gently and moulded without pressing, then salted. After a few days the young cheeses are pierced with needles so air can reach the mould and the blue veins can spread through the paste. They ripen in a cold humid room for several months, wrapped in foil for the last stage.
How long it takes: three to six months
How it is eaten
At room temperature on soda bread, crumbled into salad, or melted into a sauce for steak.
