2 tbsp infused olive oil × 9.87 mg per tbsp = 19.7 mg THC (theoretical) ÷ 8 portions = 2.47 mg per 30 g serving.

Roasting the nuts plain keeps the infused oil off the hot tray. The oil goes on afterwards, so the dose is exactly what you measured.
A bowl of these on the table is undosed snacking. Bag them.
Can I use infused butter?
Melted cannabutter works the same way; toss it through while the nuts are warm.
