Preheat your oven to 425°F (220°C).
In a mixing bowl, whisk together flour and salt.
Add the eggs and milk, whisking until smooth.
Let the batter rest for at least 30 minutes.
In a muffin tin, add a teaspoon of oil to each cup.
Place the muffin tin in the oven to heat the oil until shimmering.
Carefully remove the tin and pour the batter into each cup, filling them halfway.
Return the tin to the oven immediately.
Bake for 20-25 minutes until the puddings are puffed and golden brown.
Serve immediately with gravy or your favorite sauce.
