What is the heated brick cooking trend?

In several viral videos, a brick is heated until extremely hot and then used to infuse dishes with a smoky aroma. At first glance, it may resemble traditional Indian techniques like dhungar or tempering where hot charcoal is used to add flavour. However, there is a critical difference - charcoal used in cooking is food-safe, while construction bricks are not designed for culinary use.Also read: Heatwave Alert: 5 DIY Tests to Detect Dehydration Early

What is inside a construction brick?

Bricks may appear harmless, but they are made from clay and other raw materials that often contain industrial impurities. These can include heavy metals such as:

• Lead
• Arsenic
• Cadmium
• Chromium

These substances are invisible and do not immediately alter the taste of food, making the risk even more dangerous. When bricks are heated to high temperatures and come into contact with oil or food, these toxic elements can leach into what you eat.

Why are experts concerned?

Doctors warn that this trend is far from safe. According to nutrition experts, repeated exposure, even in small amounts, can lead to long-term health complications. Heavy metals can accumulate in the body over time and may result in:

• Damage to the brain and nervous system
• Kidney and liver dysfunction
• Hormonal imbalances
• Increased risk of chronic diseases

Unlike food poisoning, these effects are not immediate, which makes them harder to detect and more dangerous in the long run.

How does this differ from traditional cooking methods?

Traditional techniques like dhungar are carefully controlled and use food-grade materials. Charcoal is placed in a bowl, heated, and used to create smoke without directly contaminating the food. In contrast, construction bricks are industrial materials not meant for consumption. Heating them can release harmful compounds, especially when combined with oil or moisture, significantly increasing the risk of contamination.

What are the safer ways to add smoky flavour?

If you enjoy smoky flavours, there are safer and well-established alternatives:

• Use food-grade charcoal for the dhungar method
• Cook on a grill or smoker
• Add smoked spices like smoked paprika
• Try professional food-safe smoking techniques

The rise of viral food hacks has encouraged experimentation in kitchens, but not all trends are safe to follow. The heated brick cooking method highlights how easily aesthetics and novelty can overshadow basic safety principles. Experts emphasise that cooking should prioritise nourishment and safety over viral appeal. Just because a method looks innovative does not mean it is risk-free. The viral heated brick cooking trend may promise a smoky twist, but it comes with serious health risks due to potential exposure to toxic metals. Choosing safe, food-grade cooking methods is essential to protect long-term health.
