1 (generous) TBSP bacon fat (or beef drippings) per muffin cup
Directions
Combine eggs, flour, milk and salt in a medium bowl and whisk until smooth.
Cover and refrigerate for at least 30 minutes. Although they can be cooked after this it is highly recommended that you leave them to rest for at least 4-6 hours. Allow batter to stand at room temp for about 20 minutes prior to cooking.
Preheat oven to 450°
Pour (or spoon) fat into either 12 standard muffin tins or 6 deep well popover tins and place on centre rack to heat fat until nearly smoking, at least 5 minutes.
Divide batter among muffin tin wells and return pan to oven for approximately 15 minutes for regular muffin tin size or 20-22 for deeper well size.
Serve immediately with either butter and jam or as a side dish with gravy.
