Let’s Talk Cassava

One of my favorite side dishes is cassava; I make them frequently.  This exotic starchy root vegetable is very popular in the Caribbean. Furthermore, they have been prepared in a variety of ways.

What is Cassava?

Cassava is a root vegetable, also known as a root tuber. In the United States, they are commonly known as Yuca, but in some areas, they are also known as arrowroot. 
Furthermore, the root tuber can be found in a variety of different forms on the market: cassava flour, cassava cake, and cassava chips (my favorite). 

cassavaMore importantly, cassava is gluten-free and is ideal for those who follow a gluten-free diet.

Do Not Eat Cassava Raw

Cassava must be cooked. In Jamaica, cassava is used to make Bammy a type of cassava cake. I used to sit and watch my mother make bammy as a child.

The most crucial step in this recipe is to grate the cassava and extract and discard the juice. This step was said to be critical for avoiding “poisoning.”

There are two kinds of cassava, according to what I’ve heard. The “bitter cassava” should be handled with care because it is potentially dangerous. Don’t worry, the ones sold in the stores are safe to eat when cooked.

When eaten raw or in large quantities, the root vegetable can be harmful to your health because it contains cyanogenic glycosides.

In addition, this chemical has the potential to release cyanide in your body, which can impair the function of your nerves and thyroid.

Cooking Cassava is a delicious way to consume it. Furthermore, their waxy-nutty texture lends itself well to this buttery cassava sweet potato mash recipe.

  1. This looks amazing. I have seen Yuca in the store but was always afraid to buy it because I didn’t know how to use it. Now I will have to buy some so I can try this.

    Great minds think alike! I just used cassava for the first time myself by making them into fries. I love the inherent flavor that this ingredient already has. Your take is super unique and is definitely a hybrid of something like West African fufu and a more Western dish. Very nice.

  3. I’ve always wanted another way to use cassava other than our traditional Filipino cassava cake. Thank you for sharing this recipe, I’ll definitely use it to add more variety to my kid’s meals.

    Oh this looks like a MUCH tastier way of eating cassava than the bammy we had growing up- never much liked bammy, too plain for my taste. But this cassava sweet potato mash, now THAT I could devour!
