Mastering Fire Temperature Control in Asado

Fire temperature control is what separates amateur grillers from true asadores. In traditional Argentine asado, we don't use gas or thermometers—we read the fire itself.
The key is understanding coal maturity. White-hot coals are too aggressive for most cuts. You want embers with a thin layer of ash, glowing orange underneath. This gives you steady, radiant heat without flare-ups.
Create heat zones by banking coals to one side. This gives you a hot zone for searing and a cooler zone for slow cooking. For thick cuts like asado de tira (short ribs), start over high heat to develop crust, then move to the cool zone to finish.
Wood choice matters. Hardwoods like quebracho or algarrobo burn longer and hotter than softwoods. In Australia, ironbark and red gum are excellent alternatives.
The hand test is your best friend: hold your palm 15cm above the grill. If you can keep it there for 5-6 seconds, you have medium heat—perfect for most cuts. 2-3 seconds means high heat for searing.
Remember: patience is the asador's virtue. Let your fire mature, let your meat come to room temperature, and let the cooking happen slowly. This is how we honor the craft.

Excellent article! The hand test technique is something I've been using for years. I'd add that wind conditions can significantly affect heat management - on windy days, I position my parrilla to use the wind direction to my advantage.
