If you don't poke a hole in the plastic film of your TV dinner before microwaving it, you risk creating a buildup of steam inside the package. This can lead to potential safety hazards and affect the quality of the food. Here's what can happen if you don't poke a hole:
Steam buildup: As the food inside the TV dinner heats up in the microwave, it releases moisture and generates steam. If the plastic film is completely sealed without any venting, the steam can't escape, leading to pressure buildup inside the package.
Potential explosions: In extreme cases, the pressure from the steam can cause the plastic film to burst or explode. This can result in a messy and dangerous situation, potentially causing burns or injuries to anyone nearby.
Uneven heating: Without a hole to release steam, the pressure can cause the plastic film to balloon up, creating an uneven distribution of heat. This can lead to some parts of the food being overcooked while others remain undercooked.
Reduced food quality: Excessive steam and pressure inside the package can lead to a loss of texture and flavor in the food. It may become soggy or mushy, affecting the overall eating experience.
To avoid these issues, it's essential to follow the cooking instructions provided on the TV dinner packaging. Most TV dinners are designed with a venting mechanism, which is why you're often instructed to poke a hole in the plastic film before microwaving. This small puncture allows steam to escape safely during the cooking process, preventing any adverse effects and ensuring that the food cooks evenly and properly.
