In a blender combine eggs, milk, melted butter and salt. Add in flour on top. Blend until smooth. Transfer into a jug and chill for an hour or two.

Preheat oven to 190c. Put half tsp veg oil each in your Yorkshire tin. Put it in the oven. (The oil must be really hot when you pour your Yorkshire mixture in. This will immediately create the crispy skin around the mould) Fill 1/4 of the mould with the mix. Bake in the oven for 20 to 25 minutes.

Immediately remove the Yorkshiresfrom the tin. Serve straight away. (Makes 15 small Yorkshire's or 4 giant ones).
