Longe De Porc Rotie

Oven, in the book's wordsA very moderate oven

Ingredients

Directions

The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. If the pork loin is skinned, cover the top with buttered paper.

  2. If the skin is on, score it with a sharp knife in close lines.

  3. Rub the loin all over with powdered sage.

Roast

  1. Place the loin in a 350°F (175°C) oven with a small amount of boiling water in the pan.

  2. Cook slowly for 20 minutes per pound, basting frequently.

Serve

  1. When done, 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
Lean main cut that sets the structure and bulk of the dish.
Butter
Covers the top to add fat, keeping the surface moist and promoting gentle browning.
Powdered sage
Adds a savoury, herbal aroma to the meat.

The step that matters

Cook slowly and baste frequently. Pork loin is lean, so it dries out and toughens if it overcooks. A slow roast at moderate heat cooks it more evenly, and basting keeps the surface moist. The time per pound is only a guide.

Swap the sage

How well each one fits the dish's main ingredients (pork, butter):

  1. Sagethe original
  2. Thymefits about as well
  3. Garlicfits less well
  4. Parsleyfits less well

Fit is the average pairing score against pork, butter. Candidates are from the same food group and used in at least 100 recipes.
