You can make chili oil by adding dried chilis (birdseye--or any other) to the oil of your choice (olive, canola, whatever); let it sit for a while--days or weeks--and you'll get something strong, or very strong.
Add wasabi powder if you want it to be incendiary. Taste carefully, warn guests! Best served in a bottle that can't accidentally dispense tablespoons when you only want drops.
