Heat the oven to 220C/200C fan/gas 7. Place the Farmland pigs in blankets in a roasting dish with the oil and bake for 10 minutes until the bacon is golden.
Meanwhile, make the batter. Tip the flour and salt into a bowl, make a well in the middle and crack the eggs into it. Whisk together, then slowly add the milk, whisking all the time. Leave to stand.
Remove the sausages from the oven – be careful because the fat will be sizzling hot.
Pour in the batter mix, transfer to the top shelf of the oven, then cook for 20-25 minutes, until risen and golden. Do not open the oven during cooking. Serve with gravy and broccolini.
