Echil food/ drink is anyone's left over food/ drink.
We are not supposed to eat or drink echil items!
If someone sips and drinks from a cup or a tumbler, it should be washed throughly after use.
This is basic cleanliness. But I see some moms feeding their children while eating food, from the same plate or give a gulp of coffee from the same cup while drinking it!
I find this habit disgusting!!
Generally, 'Paththu' items are items which will be stale in a few hours after cooking.
Rice, sāmbār, rasam, curries, koottu are a few examples.
After touching these, we should wash our hands and then take pickles, milk, curd, ghee etc, the left overs of which are used in the following day/ days.
