Step 1: To make the batter:
Step 2: Mix eggs and milk together…whisk really well to get lots of air in.
Step 3: Gradually add the flour and salt.
Step 4: Keep whisking until mixture is really smooth. Add chopped onion.
Step 5: Put oil in Yorkshire pud tins and heat up until really hot. Add the batter. Bake at a high temperature (220ish) until risen and golden. Take out briefly and put some cheese into each pudding. Return to oven for a few mins to melt. Serve with some vegy gravy and loads of vegetables.
