Oh, you fancy, do you? Using lump charcoal made from real wood chunks? Look at you. Lump charcoal actually lasts a bit longer than briquettes because it’s less processed. But it’s even more sensitive to moisture because it has more pores and crevices for water to hide in.
Lump charcoal that’s old becomes light as a feather and snaps in your hand like a twig. It also tends to burn fast and unpredictable—like a toddler on a sugar rush. Not ideal for low-and-slow smoking.
The one exception: activated charcoal
You might have some activated charcoal sitting in your pantry for detox smoothies or teeth whitening. That stuff is a whole different beast. It’s designed to absorb toxins, so it goes bad if it absorbs moisture or odors from the air. Once it smells like last week’s curry, toss it.
Grilling charcoal, though? Technically it never becomes toxic or unsafe. It just becomes… frustrating. You’ll end up using half a bottle of lighter fluid and still waiting forty minutes for a decent flame. Is that really how you want to spend a Saturday?
