Dice veal into 2cm cubes approx.
Purge the meat by placing the Veal pieces in a pot and cover with water, bring to the boil and reduce to a simmer for 2 minutes. Pour into a colander and wash under cold water to remove the scum.

Clean the pot and return the Veal and cover with the stock, bring to the simmer and remove any fat. After 5 mins add the onion and bouquet garni. Simmer for approx. 1.5 – 2 hours until very tender. You may need to top up with extra stock. Once the Veal is cooked strain and keep the stock.

While the Veal is cooking sweat the leek in oil and pinch of salt until starts to soften. Add the thyme and butter and cook until very soft and fragrant.
Combine the leek with the veal and crumble over the blue cheese.
