All About Meat – Probing the Steak

Scared to burst the juice balloon by probing, yet unsure the steak’s done only by poking? Check out the myth of holey meat and lost juices!

Concerns exist regarding the impact of probing meat with thermometers on its moisture content. Some believe this practice, akin to puncturing a balloon, leads to precious juices escaping. However, science reveals a different story, one that empowers us to achieve optimal results without sacrificing flavor.

Meat Structure

Unlike a sealed container, a steak’s exterior does not hold its juices hostage. Moisture naturally migrates within the meat, regardless of punctures. The true concern lies in the potential damage to muscle fibrils, microscopic sheaths that store the juices we crave.

Imagine a steak’s cross-section as tightly bundled telephone wires. As heat transforms the meat, these “wires” contract, squeezing out their contents. Interestingly, the tip of a thermometer probe or even a fork is too blunt to truly pierce or sever these fibrils. At worst, it might create minor tears, leading to a negligible amount of juice loss.

This potential loss pales in comparison to the significant moisture released by overcooking the steak by just a few degrees. In fact, tools like the jaccard, designed to deliberately break down muscle fibrils for tenderness, demonstrate this principle. Contrary to the “punctured balloon” myth, jaccarded steaks cook similarly to unpunctured ones, retaining their juices effectively.

While peeking into a steak for doneness might seem tempting, it offers limited value and potentially misleading information due to the heat-induced appearance of juices.

Prioritizing Juiciness and Safety

Utilizing a thermometer, whether leave-in or instant-read, remains a crucial practice for achieving both safe and flavorful results. By understanding the minimal impact of probing and the far greater influence of cooking methods and doneness, health-conscious cooks can confidently prioritize both juiciness and culinary satisfaction.

Thermometer types

Leave-in Thermometers

While leave-in thermometers offer an initial warning, it is crucial to supplement them with temperature checks in various areas after reaching the desired finish temperature. This ensures even cooking and avoids undercooked portions.

  • Metal probes conduct heat more efficiently than meat, potentially creating “hot spots” around the probe and leading to inaccurate readings, potentially higher than actual internal temperatures.
  • Identifying the coolest area within the meat, crucial for accurate temperature readings, is challenging before cooking. Consequently, leave-in probes might provide false-high readings.

Even if the leave-in probe reaches the desired temperature, the entire roast might require additional cooking time for even internal temperatures.
Leave-in thermometers can be valuable tools for monitoring cooking progress, but they should not be the sole indicator of doneness.

Employing complementary temperature checks and considering cooking time are essential steps when we are seeking precise and safe results.

Instant-read thermometers

These are also safe to use, and the small punctures they cause are unlikely to noticeably affect moisture loss. However, avoid repeated probing, as it can let out some juices each time. Aim for 2-3 probes at most, inserted in different spots away from bone and fat.

Potential impact on juiciness

  • Frequent probing
    Continuously poking the meat with any type of thermometer can indeed release some juices. Limit probing to 2-3 times.
  • Incorrect use
    Using a fork or knife to repeatedly prod the meat creates larger holes and releases more juices compared to a thin thermometer probe. Stick to proper tools.


  • Using a thermometer doesn’t puncture meat and leak juices out.
  • Aim for 2-3 probes at most.
