Answer

Yes, in Jain household practice, chaas (buttermilk) and khichdi can generally be taken together, provided both are prepared in a Jain-appropriate way.

Explanation

Khichdi is usually made from rice and dal, and chaas is made from curd diluted with water. There is no general Jain rule that forbids eating them together.

However, keep these points in mind:

• Use fresh curd/chaas, not overly fermented or stale.
• Avoid after sunset if you follow traditional Jain food discipline.
• Ensure no root vegetables like onion, garlic, potato, etc. are used in the khichdi or tempering.
• During certain vows, tapasya, or specific observances, dairy or certain foods may be avoided depending on your rule.

Spiritual Understanding

In Jain Dharma, food is not only about taste, but also about ahimsa, freshness, simplicity, and self-restraint. Simple food like khichdi and chaas is commonly considered light and sattvic when prepared properly.

Takeaway

Yes, you may have chaas and khichdi together, as long as they are fresh, Jain-friendly, and suitable to the vows or niyams you are following.
