Stone Fruits are fruits with a stone inside, as in 1 seed only, and the seed is hard like stone.
Fruits in this category include cherries, apricots, peaches, plums, pluots and nectarines.
Mangoes, avocadoes, red dates, coconut or Lychees are drupes, although they have a stone in the middle too. Stone fruits are part of drupes but drupes are not stone fruits.
Below is a pictorial guide on how to remove the seed nicely.. and retain 2 beautiful halves of the apricot.
Apricot season is here already.... Check out your local supermarkets. I saw US grown apricots last week.
If the seed doesn't come off nicely from the other half, you have to do this.
