Whisk eggs and milk until thoroughly mixed
Add dash of salt, whisk thoroughly
Sift flour in and whisk thoroughly - NO LUMPS!
Set batter aside for 30+ minutes
Place approximately 1 tsp of vegetable oil (bacon fat, lard, etc.) in bottom of each cup and place in oven
Heat oven to 450F
Remove the tin from oven (it should be very hot!)
Place equal amounts of batter in each cup (should get a bit of a sizzle from the hot fat/oil)
Bake for 20-25 min until fluffy and brown
