How to pick a perfect watermelon:

Few things to keep in mind are –

  • Consume the fruit in its specific season that is during summers specially from May to August.
  • Consume the ripened fruit not the semi ripened one. If it is not properly ripened it is not proper sweet and the flesh will become soft and bit soggy and will not have so much flavour and taste. We can check this by seeing the stem. If the stem is small and brown it is better. But if the stem is green, it means the fruit is not fully ripened.
  • The tiger striped pattern with dark green stripes to be specific are better.
  • It should be heavy and large, if its light then it means that it has started to become dry and less juicy.
