Beat the fat of choice until “foamy”.
Add bit by bit whatever sugar is salvageable from the floor and as many eggs as the hen lay this morning, one at a time.
Mix, sift and stir in the flour, baking powder and salt.
Add your desired quantity of milk if the batter is too thick.
Pour the batter into a greased pan. Smooth.
Make multiple small incisions lengthwise on the outside of the quartered apple. Place quarters onto batter.
Bake 35-40 minutes at 400° (200°C). (The actual recipe even gives a recommended temperature range of 400-430°, depending on how many logs you’ve thrown in the old wood-burning oven?)
When cool, sprinkle with powdered sugar.
