During Paryushan, fresh paneer is generally not allowed in a Jain diet, because foods involving curdling or fermentation (and certain dairy products) are avoided to keep the meal very simple and sattvic.

What you can do instead (Paryushan-friendly, simple ideas):

• Eat fresh, easily digestible vegetarian foods prepared the same day.
• Use allowed vegetables and pulses that are not root vegetables or greens, as your local tradition permits.
• Rely on boiled water, daylight meals, and simple preparations like khichdi made from acceptable grains and pulses, plain lentil dishes, or roasted/dried fruits and (if your tradition allows) dry fruits.

If you’re looking for specific recipe ideas that fit Paryushan rules, your local guru or sangh can provide a list tailored to your tradition.
