Answer

Yes, generally Jains can use black pepper.

Explanation

Black pepper is a plant-based spice and is not considered a prohibited food in Jain dietary practice. It is commonly used in Jain cooking.

Spiritual Understanding

In Jain Dharma, the main food restrictions focus on avoiding harm to living beings as much as possible. Black pepper is accepted because it is a spice used from the plant and does not involve the same level of harm as root vegetables or other restricted items.

Takeaway

So, black pepper is usually fine for Jains. The only caution is to ensure it is used in pure Jain food, without mixing with non-vegetarian or prohibited ingredients.
