Why it works: Pepper and ginger match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 6,800 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the pork
Clean the pig's fore leg and cut into small bite-sized pieces; shred the red pepper.
Heat a wok with plenty of water and add the pig's fore leg pieces.
When the water boils again, reduce to low heat and cook for 45 minutes.
Drain the pig's fore leg and rinse the fat with clear water.
Soak the cooked pig's fore leg in clear water for 1 hour.
Heat the wok with 500 ml of water and cook the pig's fore leg for 30 minutes.
Drain and rinse again, then soak in chilled cold clear water for 30 minutes.
Make the sauce and marinate
Transfer the cooked pig's fore leg pieces to a large container.
Heat the wok and boil the sauce, then let it cool.
Pour the cooled sauce into the container with the pig's fore leg.
Add the shredded red pepper, then chill in the refrigerator for 12 hours.
Serve
Serve after removing from the refrigerator 2 hours earlier.
Nutrition, whole recipe (rough)
Counts 5 of 7 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig's fore leg
- Provides the meat and fat that form the main body of the dish.
- White vinegar
- Adds acidity that brightens the sauce and balances the sweetness.
- Sugar
- Adds sweetness that balances the vinegar and salt in the sauce.
- Red pepper
- Adds fresh colour and mild aroma to the chilled dish.
The step that matters
Rinsing and soaking the cooked pork. Repeated draining, rinsing and soaking in cold water removes surface fat and loose residue, which keeps the final dish clean-tasting and less greasy.
Swap the ginger
How well each one fits the dish's main ingredients (pepper, sauce, vinegar, sugar):
- Tarragonfits better
- Gingerthe original
- Cinnamonfits about as well
- Allspicefits about as well
Fit is the average pairing score against pepper, sauce, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
