Secret Ingredient Makes the BEST Rhubarb Crisp Ever! 🤫🤫

Rhubarb season is fleeting, so when those vibrant pink stalks appear, it’s time to whip up some delicious treats! But have you ever wondered what that secret ingredient is that makes some rhubarb crisps absolutely irresistible? The one that takes them from good to absolutely mouth-watering?

Enter: Cornstarch! 🌽

That’s right, the humble cornstarch is often the unsung hero in many a stellar rhubarb crisp. This versatile ingredient plays a crucial role in creating the perfect texture and flavor balance.

But how does cornstarch work its magic?

When cornstarch is mixed with liquid (in this case, the juicy rhubarb and drippings from the fruit), it forms a gel. This gel helps to thicken the filling, creating a satisfyingly creamy center that complements the crispy topping. It also traps the juicy flavors of the rhubarb, ensuring they’re evenly distributed throughout the crisp.

Think of cornstarch as a magical sponge. It absorbs excess liquid, leaving you with a delightful balance of juicy sweetness and comforting crispness.

Here’s how to achieve rhubarb crisp perfection with cornstarch:

  • Mix the cornstarch with a cold liquid (such as milk or water) before adding it to the fruit filling. This prevents lumps and ensures a smooth, velvety texture.
  • Use the right amount of cornstarch. Less cornstarch will result in a looser filling, while too much will leave the crisp dry and starchy.
  • Don’t be afraid to experiment! Try adding spices like cinnamon or nutmeg to the cornstarch mixture for an extra delicious twist.

Beyond the classic crisp, cornstarch’s versatility shines in other rhubarb treats:

  • Rhubarb cobblers and pies: A cornstarch slurry thickens the fruit base, creating a delicious jiggly center.
  • Rhubarb smoothies and yogurt bowls: A touch of cornstarch can help to thicken and stabilize the fruit, preventing it from turning watery.

So, the next time you’re craving a sweet and cozy treat, don’t underestimate the power of a humble cornstarch. It just might be the secret ingredient that takes your rhubarb experience to the next level!


The humble rhubarb, with its vibrant color and sweet-tart flavor, is a true delight in the spring and summer months. And while its deliciousness is undeniable, achieving the perfect crisp texture can sometimes be a challenge. But fret not, for there is a secret ingredient that can elevate your rhubarb crisp to new heights of deliciousness! By incorporating this simple addition, you can ensure a delightful crunch that will have your taste buds singing. So, gather your ingredients, embrace the season, and create a rhubarb crisp that truly stands out.
