Cornstarch chunk is a tasty and crunchy snack popular in many parts of the world. It’s made from cornstarch. Making them at home is simple and allows you to customize the flavor as much as you like!

The method I’ve shown below will help you to make the perfect, crispy and crunchy cornstarch chunks.

How to Make Cornstarch Chunks

What are Cornstarch Chunks?

Cornstarch chunks, also known as cornstarch bricks or cookies, are a unique snack that you might find intriguing. They’re simply cornstarch that’s been compacted and processed into a solid, chunky form.

Imagine this: you take a bite and experience an unexpected crunch. That’s the charm of cornstarch chunks! Some people absolutely love this sensory experience, comparing it to the satisfaction of biting into other crunchy snacks.

The process of creating these chunks involves you packing cornstarch tightly, baking it, and then freezing it. The result? A hard, crunchy texture that’s quite different from the powdery cornstarch you started with.

But before you dive in, remember this: cornstarch is a type of carbohydrate that doesn’t pack a lot of nutritional punch beyond providing energy. And if you get too carried away, eating large amounts can lead to some uncomfortable digestive issues. So, as with all things, enjoy your homemade cornstarch chunks in moderation.

What does it taste like?

A cornstarch chunk has a fairly neutral taste, much like the cornstarch it’s made from. The flavor is light and slightly grainy, but essentially plain.

However, its blandness can be a positive attribute as it provides a blank canvas for you to get creative with your favorite flavors.

Whether you want to add a dash of vanilla extract, a sprinkle of cinnamon, or even some cocoa powder, the choice is yours.

It’s all about the texture with cornstarch chunks – they start off with a firm crunch and then dissolve into a smooth, almost creamy consistency in your mouth.

It’s this unique textural experience that makes tasting cornstarch chunks a culinary adventure!

Step-by-step instructions

Step 1

First, pour 300 grams of your preferred cornstarch into a paper packet. It’s just the right amount to satisfy your crunchy cravings.

Step 2

Give the packet a good shake and tap it a few times. You’re making sure there’s no air left inside with the cornstarch.

Step 3

Now, wrap the packet as tightly as you can. Apply some muscle and make sure it’s completely air-tight.

Step 4

Next up, wrap the packet in aluminum foil. Again, you’re aiming for an air-tight seal.

Step 5

Preheat your oven to 375°F (190°C). This is the perfect temperature to transform your cornstarch into a delicious treat.

Step 6

Place your well-wrapped packet in a baking dish and let it bake for 2 hours. This is where the magic happens!

Step 7

Once it’s done baking, carefully remove the packet from the oven and let it cool down to room temperature. Patience is key here!

Step 8

After it’s cooled, place your packet in the freezer for 4 hours. This will give your cornstarch that extra crunch.

Step 9

Now, the moment you’ve been waiting for! Take the packet out of the freezer and unwrap the foil.

Step 10

Remove the cornstarch chunk from the paper packet. Break it into pieces that are just the right size for you.

Step 11

Voilà! Your crunchy cornstarch is ready for you to enjoy. You’ve made this all by yourself!

How to store Cornstarch Chunks?

Storing cornstarch chunks properly is essential to maintain their texture and prevent them from going stale. Here’s how you can do it:

Check Regularly: Make sure to check the chunks regularly for any signs of moisture or mold, especially if you live in a humid climate.
