National Chocolate Covered Cashew Day is observed worldwide on April 21 each year. This day celebrates the delightful combination of chocolate and cashews, encouraging people to enjoy this special treat. Cashew trees, which originate in Brazil, produce cashew apples along with the nuts, and the fruit can be eaten fresh or used to make beverages. It's important to note that the shell of the cashew nut is toxic, which is why they are sold shelled to consumers. Additionally, an interesting fact about raw cashew nuts is that they are highly flammable and can produce tiny explosions when tossed into an open fire, although this should only be done outdoors and under adult supervision.
