Peel the potatoes before slicing into similar sized shapes. Add them to a pan with cold water along with a good pinch of salt. Bring to the boil and cook for 10 minutes.
In the meantime, add around 3-4 tbsp of goose fat to a roasting dish and place in the oven for ten minutes.
Once you can pierce the potato with a knife, drain and cover with a tea towel for 5-10 minutes.
Next, give them a good shake to fluff up and carefully tip into the hot oil and spread evenly. Season with salt and pepper before whacking in the oven for 30 minutes.
After 30 minutes, turn them, add a bulb of garlic, a drizzle of extra virgin olive oil, fresh rosemary and lemon peel. Place back in the oven for another 30-40 minutes. This method will guarantee the most delicious roast potatoes. Crunchy on the outside, nice and fluffy on the inside.
