I worked with a colleague (retirement age). He spent his childhood in places where peanuts were grown.

We asked him once:

-Victor Palych, here you all childhood grew up on the "barrel", tell me how to choose a garlic

-Now guys.. (everyone was silent, listened, remember the tail not the tail, the net, the boy / girl). You go past watermelons, take care of yourself, then “smell” it, break it, try it. If it is delicious, you eat; if not, you take another. There are no more secrets.
