Why Do Gas Grills No Longer Use lava Rocks For Cooking?
In the past, gas grills often used lava rocks by default. However, this changed over time as manufacturers use the latest technology. Here are the reasons why manufacturers replaced lava rocks in gas grills:
Lava rocks are porous and come from volcanic eruptions. Since these rocks are porous, the drippings of oil, grease, and food remain on the rocks. Lava rocks absorb these drippings and may cause the building up of harmful bacteria if you don't clean the grills and the lava rocks well.
If you use the uncleaned lava rocks and the smoke they create touches your food, contamination may arise and that is a health risk. You should replace the lava rocks if they accumulate too much oil and grease.
Too much grease and oil on lava rocks and around the gas grill will result in excessive smoke. Charred food has carcinogens, and extreme charring of food may increase the threat to health. Cleaning the grill and regularly replacing the rocks may reduce the health risk.
Why Use Lava Rocks In Gas Grills?
While manufacturers have moved away from including lava rocks, here are the reasons why lava rocks are still great for gas grills:
- Lava rocks preserve temperatures longer than charcoal and retain heat.
- You can reuse the lava rocks in grilling multiple times. You need to clean them after use through heating and wash them with water. Let them dry before using them again for the next grilling session.
- Oil and grease drip on the grill surface. Lava rocks absorb fats, which prevent unwanted combustion.
What Type Of Gas Should You Use Lava Rocks On?
Aside from natural gas, propane gas is also ideal to use because it emits too much heat. Lava rock will equally distribute the heat propane gas produced. The question is, can you use propane gas in a natural gas grill? The answer is yes if the manufacturer stated that the grill could hold propane. Refer to your manufacturer's user manual for further instructions.
