Cornstarch Slurry

First off, what is this magical concoction? Cornstarch slurry is essentially a simple mixture of cornstarch and water. It’s as easy as 1, 2, 3. Mix equal parts of cornstarch and cold water, give it a good stir, and voilà, you’ve got yourself a cornstarch slurry.

One of the most common uses for cornstarch slurry is as a thickening agent. If you’ve ever made stir-fries, sauces, or soups, you know that achieving the perfect consistency can be a bit tricky. This is where our hero steps in. When added to a simmering liquid, the starch particles in the slurry swell and thicken the sauce, turning it into a glossy, velvety masterpiece. No more runny, sad sauces!

Cornstarch slurry doesn’t just thicken; it also adds a beautiful sheen to your dishes. If you want your gravies and sauces to look like they belong in a five-star restaurant, this is your secret weapon.

Ever find yourself with an overly salty or spicy dish? We’ve all been there. Don’t worry; cornstarch slurry can save the day. Just add a bit to your too-intense dish to dilute the flavors and bring things back to a balanced state.

Frequently asked questions

Can I store leftover corn starch slurry?

While it is best to use the slurry immediately, you can store any leftovers in an airtight container in the refrigerator for a short period. Before using it again, give it a good stir as it may separate.

Is corn starch slurry gluten-free?

Yes, corn starch is gluten-free, making it a safe option for those with gluten sensitivities or celiac disease.

Can I reheat dishes thickened with cornstarch slurry?

Yes, you can reheat dishes that have been thickened with cornstarch slurry. However, be aware that excessive reheating may cause the slurry to break down, affecting the consistency of the dish.

Can I adjust the thickness of the slurry?

Absolutely! If you desire a thicker slurry, increase the amount of corn starch in the mixture.

  • Add 2 tablespoons of cold water to the bowl containing the cornstarch.

Notes

  • You don’t have to add the additional water to the slurry it just makes it easy to add to a recipe. Most recipes are gone to tell you the amount of water and corn starch to mix to make your slurry, so follow the recipe.
  • In generally if you are trying to thicken something like a soup, I start with 2 tablespoons of cornstarch and 1/4 cup or cold water for my slurry and let it go in the dish before adding more. 
  • This is great as a thickening agent in sauces, soups, or any other recipes that need thickening. When mixing the slurry into your dish, add it slowly to prevent clumping.
