Preheat your oven to 220°C/200°C fan/425°F.
Add just around a tsp of oil to each of the holes in the muffin tin.
Place your tin in the oven for 10-15 minutes until the oil is super hot, basically spitting!
Whilst your oil is heating, beat/whisk your 6 eggs into your cornflour in a big mixing bowl.
Once thoroughly combined, gradually add your milk a little at a time. Mix together.
Pour your Yorkshire pudding batter into a jug so it's easier to pour into each hole.
Remove your muffin tray from the oven and immediately fill each hole with your mixture until just under ¾ full.
Place back in the oven and bake for around 15–20 minutes until golden and risen.
Remove from your oven once cooked and serve up with a delicious roast dinner.
