As you sit at the breakfast table with your head about to drop flat into your cereal, you are gently woken up by “Snap, Crackle, Pop” the sweet sound of morning. How is it that Rice Krispies can serve as the perfect alarm clock?

The sound is so sweet that in 1963 the popular band, the Rolling Stones, recorded a short song for a Rice Krispies advertisement.

Did You Know?
The characters of Rice Krispies play a role outside of being cereal endorses. Snap is a baker, Pop is a soldier, and Crackle is a band leader.

Raw, unprocessed rice is a type of whole cereal grain. Each whole grain of rice or cereal is composed of outer protective layers called the chaff and bran; a bulky body called the endosperm, which is laden with starch; and a small germ, which is the reproductive part of the grain. To get white rice, the bran and germ is removed in processing, leaving only the starchy endosperm. Rice Krispies are created from a method of cooking white rice so that it puffs and crisps up to a light and airy texture. Initially, white rice needs to be steam conditioned to get enough moisture into the rice grain. Then, the steamed white rice is heated in an oven, causing the moisture and starch within the endosperm to react and expand to form thin hollowed out walls that are crunchy and crispy. The famous “snap, crackle, pop” that tickles your ears occurs when milk is poured over Rice Krispies is a result of the walls collapsing as they soak up the milk.

Fast Fact: Popcorn is created in the same way that Rice Krispies are, except that corn has more moisture in it and does not need to be steam conditioned and the reaction of corn popping is much for dramatic than popping rice.

Nutritionally, Rice Krispies compared to regular cooked white rice has added sugar, but if you were to consume equal serving sizes (i.e ½ cup) of both you are more likely to consume less calories from Rice Krispies simply because of the increased volume of crisped rice.

Fast Fact: One cup of Rice Krispies cereal provides a one ounce serving of grains.

As the popularity of Rice Krispies increased over the years, Kellogg’s has modified the original cereal. To date, Cocoa Krispies, Rice Krispies Treat Cereal and Rice Krispies with Vanilla flavouring (only sold in Canada) are currently available on the market.
