Yorkshire is originated from England and it is something quite similar to popover, which is called the American yorkshire. However, I went through checking out the making of yorkshire on Gordon Ramsey page and also on The Spruce, and both are very informative which helps a lot in the making. Please read on for more.
1 cup full cream milk
1 cup all purpose flour
1 tspn vanilla essence/extract
a pinch of salt
* some cold butter diced
(1) beat the egg together in a mixing bowl then shift in the flour & salt to make it a smooth batter.
(2) next, whisk in the milk till combined, then transfer to a large measuring cup & set aside to rest for an hour.
(3) when ready, preheat oven at 250'C and place diced butter to each muffin cups and put tray into oven for 15 minutes or till butter turns really hot which will help the rising.
(4) now carefully pour batter to hot muffin cups then put tray straight back to the oven and let to bake for 15 minutes or till risen & turns golden brown. Do not withdraw tray from oven, just slide out the tray and fill in the batter then push it back straight.
