Answer

In most Jain traditions, pink Himalayan salt is not allowed in ayambil because it is still salt.

Explanation

Ayambil is meant to be a very simple and tasteless austerity. In many traditions, the food is prepared without salt, oil, ghee, spices, sugar, and other taste-enhancing items. So even though it is “natural” salt, pink Himalayan salt is still considered salt and is usually avoided.

Spiritual Understanding

Ayambil helps reduce attachment to taste and food pleasure. The purpose is to support:

• simplicity
• control of senses
• detachment
• inner purity

So the rule is generally followed strictly, according to the tradition of the sangh or guru.

Takeaway

Usually, no — pink Himalayan salt is not allowed in ayambil. If your local Jain tradition has a specific rule, follow that guidance strictly.
