Chop the beef into bite-sized cubes, season with 4g Salt and 2g Black Pepper, then rub in 50g of Plain Flour
Heat 15g of Olive Oil in a large pan, and fry the beef in batches until browned off. Before transferring it to a large thick-bottomed cooking pot, along with one bottle of Guinness
Using the same pan you used to brown the meat, heat the remaining15g of Olive Oil, and fry 400g of onions on a medium heat until translucent, then add 40g garlic and continue to cook for a further minute
Add 60g of balsamic vinegar to caramelize the onion and garlic, and fry for around 3 minutes, then toss the whole thing in with the beef and Guinness
Using the second bottle of Guinness, de-glaze the pan (Put it back on the heat and use the liquid to rescue all of the delicious flavours left behind after frying everything). Pour into the main cooking pot and discard the pan
Put the meat, onions and Guinness filled pot on a medium heat, then add 150g leeks, 300g carrots and 150g celery, and cook for ten minutes
Add 300g of chicken stock, stir, then pour in around a litre of water
Next, drop in 20g of soy sauce along with 4g of fresh thyme, 2g of fresh rosemary and 6 bay leaves. Then simmer for 30 minutes
Taste the glorious liquid, then add more salt/pepper/rosemary/thyme/ as required. Remember that the flavours will become stronger as the stew boils down
Cover with a lid, and continue to simmer for however long the beef takes to soften, usually around 3-4 hours, adding more water if it begins to thicken
When the meat has reached its melt-in-the-mouth phase, boil down the concoction so the sauce is nice and thick (too liquidy and it’ll soak into the pastry and make your pies collapse)
Right at the very end, drop in 40g of Unsalted Butter, and stir until thoroughly absorbed
Set aside and leave to cool (can be refrigerated for up to a week, or frozen for a month)
