Crack the eggs into a medium sized mixing bowl and whisk until beginning to bubble. Add the milk and whisk again. Next add the flour and salt and whisk again until smooth.
Pour the mixture through a sieve into a jug and set aside.
Place the muffin tray on top of a baking tray and pour EVOO into the base of each muffin slot. Pour enough oil to cover the base well. Place the tray into a pre-heated oven 190 °C for 8 minutes
At the same time heat a frypan over medium high heat and add a splash of oil, season the steak and pan fry on both sides until medium rare
Finely chop the parsley leaves and set aside
Once the steak is cooked remove from the heat and set aside to rest and cool slightly
Remove the tray from the oven and pour the pudding mix into each slot in the muffin tray. Fill almost to the brim and ensure no mixture spills onto the outer parts of the tray and that the slots are not overfilled and brimming over.
Place the tray back in the oven combi setting 190 °C for 15-18 minutes
Once baked remove the tray from the oven and remove the puddings from the muffin mould and place on a cake rack to cool.
Top up the oil if required in the muffin tray and return the muffin tray to the oven and repeat the process with the remaining pudding mix.
Once all the puddings are baked finely slice the beef into small strips, place one beef strip into each pudding, top with a small piece of blue cheese and scatter over chopped parsley and serve.
