Roast Loin of Pork

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 the pork

Trim and score the loin of pork, separating the bones with a small chopper or meat saw.
Make an incision in the upper part of the loin for stuffing, sew it up with twine, and skewer it lengthwise.

Make the stuffing

Prepare the stuffing by boiling chopped sage and onions in water for 3 minutes, then drain.
In a pan, combine the drained mixture with pepper, salt, and butter, and simmer gently for 10 minutes.

Roast and serve

Stuff the pork with the prepared stuffing before roasting.
Roast the pork for about 1 hour and 15 minutes at 400°F (200°C).
Dish up the pork, pour brown gravy underneath, and garnish with fried small potatoes.
Serve with apple sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Pork loin: Forms the main cut of meat, which is roasted whole and carved for serving.
Onions: Soften during boiling and add sweetness and moisture to the stuffing.
Butter: Adds fat and richness to the stuffing mixture.
Sage: Contributes a herbal aroma that complements the pork and stuffing.

The step that matters

Roast the pork for about 1 hour and 15 minutes at 400°F (200°C). Roasting at a high temperature browns the surface and renders fat, while the pork must reach a safe internal temperature without drying out. Checking doneness rather than relying only on time helps avoid overcooking a lean loin.
