Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork loin
- Provides the meat, which browns for savory flavor and stays tender when cut thin.
- Pineapple chunks
- Adds fruity sweetness and juice that moistens and flavors the sauce.
- Vinegar
- Adds acidity that balances the sweetness of the sugar and pineapple.
- Brown sugar
- Adds sweetness and a caramel note that rounds out the sour flavors.
- Cornstarch
- Thickens the sauce into a glossy coating when heated with liquid.
- Soy sauce
- Adds savory, salty depth that gives the sauce body.
The step that matters
Thickening the sauce with cornstarch. Cornstarch only thickens once it is heated with liquid until the starch granules swell. Stir the sauce as it heats and cook until it turns clear and slightly thick, or it will stay thin or clump.
Swap the pineapple
