Name: Chinese Deep-fried Stuffed Green Peppers
Ingredients: 4 green peppers; 2 eggs, separated; 9 oz (250 g) lean boneless pork; 2 tsp flour; ½ tsp scallions, chopped; ½ tsp cornstarch (cornflour); ½ tsp fresh ginger, chopped; 2 cups vegetable oil for deep-frying; 1 tsp salt, or to taste; ½ tsp spiced pepper-salt; 1 tbsp soy sauce; ¼ tsp msg (optional); ¼ tsp five-spice powder

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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green peppers: Hold the pork filling and provide the tender, slightly bitter vegetable body of the dish.
Pork: Forms the savoury filling that is bound and cooked inside each pepper piece.
Eggs: Whites with flour and cornstarch form a batter that puffs and crisps when fried; yolks add richness.
Cornstarch: Creates a light, crisp coating that stays crunchy after frying.
Flour: Dusted on the filled side and mixed into the batter to help the coating adhere and brown.
Soy sauce: Adds salty, savoury flavour and colour to the pork filling.

The step that matters

Holding the oil at 350°F (175°C). If the oil is too cool, the batter absorbs oil and turns greasy; if too hot, the coating browns before the pork and pepper cook through. Steady heat gives a crisp, evenly cooked result.
