Step 1

To make the batter, mix the flour and mustard powder in a bowl with a good pinch of salt. Gradually whisk in the eggs and milk until you have a smooth batter. Mix in the thyme.

Step 2

Heat the oven to 220C/fan 200C/gas Fry the sausages in the oil until golden brown. Put the sausages and any oil in the bottom of an ovenproof dish (you’ll need one where you can arrange the sausages evenly with enough space between them for the batter to rise).

Step 3

Put the dish in the oven for 5 minutes to heat. Give the batter another whisk then pour into the hot dish. Put straight back in the oven and cook for 30 minutes until puffed, browned and crisp.
