Paheli watched grandmother making mango pickle.

Question:

Paheli watched grandmother making mango pickle. After she bottled the pickle, her grandmother poured oil on top of the pickle before

closing the lid. Paheli wanted to know why oil was poured? Can you help her understand why?

Solution:

The oil poured on the pickle forms a barrier between the pickle and air. This prevents the bacteria present in air from entering jar and attacking the

pickle and spoiling it. Thus, increasing the shelf life of pickles.
