Yes, you can warm up corn on the cob in the microwave. While the microwave is known for sometimes drying out leftovers, a specific technique can be used to maintain the corn’s moisture and texture. The key to success is creating a small, steamy environment around the cob to prevent the kernels from becoming rubbery or tough. You can quickly enjoy warm, juicy corn that tastes nearly as fresh as when it was first cooked. This method is particularly useful when you only need to reheat one or two ears of corn.
The Quickest Way to Reheat Corn on the Cob
Begin by preparing a paper towel, dampening it with water until it is moist but not dripping wet. This damp towel will generate the necessary steam during the heating process. Wrap the ear of corn completely in the damp paper towel, ensuring the entire surface of the kernels is covered.
Place the wrapped corn on a microwave-safe plate and set the appliance to a medium power level, specifically 50% power, rather than using the high setting. Using a lower power setting helps the corn heat more evenly from the center of the cob outward, which prevents the outer kernels from overcooking and turning rubbery before the inside is warm. For a single ear of corn, start with a heating time of 30 seconds to one minute.
After the initial heating period, carefully flip the wrapped corn over to ensure heat is distributed to all sides. Continue heating in short bursts of 20 to 30 seconds, checking the temperature after each interval. Once the corn is warm to the touch, allow it to rest on the counter for about one minute, letting the residual heat finish warming the center of the cob.
Tips for Preventing Dryness and Ensuring Safety
The damp paper towel acts as a miniature steamer basket, trapping the water vapor released from the towel and the corn itself. This trapped steam circulates around the kernels, which helps to rehydrate the surface. It also prevents the natural sugars within the corn from caramelizing too quickly, which leads to a tough, chewy texture.
To further enhance the flavor and moisture, apply a small pat of butter or a light sprinkle of water directly onto the corn kernels before wrapping them in the damp paper towel. This provides extra moisture, resulting in a richer taste and a more tender kernel. The corn is ready when the kernels feel hot all the way around the cob, but they should still retain a slight snap when gently pressed.
A significant safety consideration when using this technique is the steam that has been trapped inside the paper towel wrapping. The steam will be extremely hot and can cause burns if the wrapping is removed too quickly. To safely unwrap the corn, use tongs or a fork to hold the cob and carefully peel back the paper towel, directing the escaping steam away from your face and hands. This simple precaution ensures you can enjoy your perfectly reheated corn without incident.
