Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pork, Loin Of, Baked
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pork
Score the skin of the pork in narrow lines and brush it with salad oil.
Bake and serve
Bake in a moderate oven at 350°F (175°C) for 40 minutes.
Add the potatoes, apples, and onions to the tin with the meat.
Continue to cook gently for 1 to 1.5 hours.
Arrange the vegetables and apples on a hot dish, place the meat in the center, and serve the gravy separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork loin
- Provides the main meat, whose fat and skin render and crisp during roasting.
- Potatoes
- Absorb roasting juices and turn tender and starchy, adding bulk to the dish.
- Apples
- Soften and turn slightly sweet as they cook, balancing the rich pork.
- Onions
- Soften and turn sweet as they roast, adding savory depth to the pan juices.
The step that matters
Continue to cook gently for 1 to 1.5 hours. Cooking at a steady moderate heat lets the pork cook through without drying out while the potatoes, apples, and onions become tender. Pork is safest when cooked to a consistent internal temperature, so checking doneness rather than relying on time alone helps avoid undercooked or overly dry meat.
Swap the apple
How well each one fits the dish's main ingredients (pork, potato, onion):
- Avocadofits better
- Coconutfits better
- Mangofits about as well
- Applethe original
Fit is the average pairing score against pork, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
