Why it works: Basil and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,768 recipes mention both. Both carry terpineol, which smells pine, woody. The science ↓
The recipe
Serves 4Ingredients
Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the vegetables
Cut asparagus stalks in half crosswise and place in large bowl.
Add red pepper, zucchini, basil, parsley, and garlic. Toss together to combine.
Lay out four large pieces of foil and divide bok choy among them.
Top with asparagus mixture; set aside.
Coat the salmon
In a small bowl, whisk together mustard, oil, thyme, and pepper.
Add salmon and turn to coat evenly.
Assemble and grill
Place one piece of salmon on top of the bok choy-asparagus mixture.
Fold foil to seal or place another piece of foil on top to seal and form packets.
Place packets on a greased grill over medium heat and cook for about 10 minutes.
Use a digital food thermometer to check that the salmon has reached an internal temperature of 70°C (158°F).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon fillets
- Provides the main protein, which firms and turns opaque as it cooks in the packet.
- Dijon mustard
- Adds sharp, tangy flavour and helps the herb and oil coating cling to the fish.
- Vegetable oil
- Carries the herbs and mustard and keeps the salmon moist during cooking.
- Asparagus
- Adds tender-crisp texture and fresh, green flavour as it steams in the packet.
- Zucchini
- Releases moisture as it steams, adding softness and mild sweetness to the packet.
- Red bell pepper
- Adds sweetness and colour, softening as it steams in the foil.
The step that matters
Check the salmon with a thermometer. Salmon can dry out or stay underdone because thickness and grill heat vary. A thermometer shows when the fish is cooked through, while the sealed packet holds in steam that keeps it moist.

Fit is the average pairing score against asparagus, pepper, basil, parsley, garlic, mustard, thyme. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
