The recipe
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 400°F (200°C).
Remove some kidney fat from the loin and paper the skin.
Roast and serve
Roast the loin for three hours, ensuring both ends are browned.
If desired, roast the kidney separately in the dripping pan for better browning.
Once browned, place the kidney on thick toast in the dripping pan to absorb the fat.
Serve the toast and kidney on a separate dish without gravy.

What each ingredient does
- Calf loin
- Forms the main roast, cooking slowly to become tender and evenly browned.
- Kidney fat
- Adds richness and moisture, and its fat carries flavour into the dish.
- Thick toast
- Soaks up the rendered fat from the kidney, giving a rich, savoury base.
The step that matters
Ensuring both ends are browned. Browning depends on dry surface heat reacting with proteins and sugars, so uneven heat or moisture leaves pale patches. Turning the roast helps even the colour and flavour.
