During lockdown citizens have some more time for cooking

With Covid-19 cases increasing almost no restaurant is offering lunch in some areas. People are also reducing the time they spend outdoors. Earlier it was easy to get food from a local restaurant, now people are forced to cook their food at home.
Many people who had very less experience in cooking are now learning to cook.
Though this will take some time, the main advantage is that the cook has control over the ingredients used and can ensure that no oil is used.
