Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pork Pie
Ingredients
Directions
Cut the pork into small dice and season with salt and pepper.
Place the bones in a pot, add the onion, salt, and pepper, cover with cold water, and simmer for at least 2 hours to extract the gelatin.
Put the flour in a large bowl and add a pinch of salt.
Boil the lard and water together for 5 minutes, then add to the flour, stirring until cool enough to knead.
Knead the mixture until smooth, cover with a cloth, and let it sit near a warm place for about 1 hour.
Re-knead the paste, set aside about ¼ for the lid, and shape the rest into a round or oval form.
If needed, use a small jar in the center to help mold the paste.
