Answer

Yes, Jains can generally eat homemade idli and sambar if it is prepared without onion, garlic, and any root vegetables.

Explanation

Idli is usually made from:

• Rice
• Urad dal
• Water
• Salt

These ingredients are generally acceptable in Jain diet, depending on family and sect practices.

Sambar can also be Jain-friendly if it avoids:

• Onion
• Garlic
• Potato
• Carrot
• Radish
• Beetroot
• Other root vegetables

It may be made with non-root vegetables such as:

• Bottle gourd
• Drumstick
• Tomato, if accepted in your family tradition
• Brinjal, if accepted
• Pumpkin
• Beans, if accepted

Important Jain Considerations

• Fermentation: Idli batter is fermented. Many Jains do eat fermented foods in regular household practice, but some stricter Jains may avoid them, especially during certain religious observances.
• Time of eating: Jain discipline traditionally avoids eating after sunset.
• Paryushan / Ayambil / Tapasya: During religious vows or stricter observances, idli-sambar may not be suitable depending on the rules being followed.
• Family tradition: Some Jain families have additional restrictions beyond the common rules.

Takeaway

Homemade idli-sambar without onion, garlic, and root vegetables is generally acceptable for many Jains, but stricter practice may avoid fermented idli batter or certain ingredients depending on vows, festivals, or family tradition.
