Preheat the oven to 450 degrees. In a medium size bowl, whisk eggs and milk together. Add flour and whisk until incorporated and few lumps remain. Add melted butter and whisk until there are no more lumps.
Add 1/4 tablespoon of vegetable oil in the bottom of each pan. Place your popover pan into the oven for 5 minutes until the oil gets hot and begins to smoke.
Remove the hot pan and evenly pour the batter until it comes about 3/4 up pan. Pour quickly and place the pan back in the oven. Bake for 20 minutes and then turn the heat down to 350 degrees and bake for another 10 minutes.
Remove the pan from the oven and remove the popovers lightly spraying the top of popover and rolling the sprayed top in a plate of everything seasoning. Use your fingers to sprinkle on any areas that aren’t covered. Place the popover back in the popover pan and repeat with the remaining popovers.
Place them back in the oven for about 2 minutes. Remove and serve.
