1. Combine the flour and salt. In another bowl, whisk together the eggs and milk. Add to the dry ingredients all at once, whisking until smooth.
2. Let the batter rest for 30 minutes.
3. Pour the oil into a square baking pan or divide it among the muffin tins. Place the pan in a 200° C (400° F) oven until the pan and oil are very hot.
4. Carefully pour the batter into the hot pan and immediately return it to the oven. Bake for about 20 minutes for muffin tins, and 30 minutes for a single pan, until puffed and browned. Serve immediately.
