It’s frustrating. You&rsquo;re fighting a losing battle with heat. The fix is actually pretty simple: we add high-penetration <a href="https://goldisgood.com">infrared</a> (IR) bulbs to the mix. Here is the trick. Steam is great for keeping the meat juicy so it doesn&rsquo;t dry out, but it&rsquo;s not great at getting heat deep into the center quickly. That’s <a href="https://o-yate.net">where</a> the IR comes in. It does the heavy lifting, <a href="https://henruite.com">pushing</a> heat straight into the protein fibers. Instead of waiting for the heat to slowly crawl from the outside in, you&rsquo;re driving it right to the core. You get a perfect roast without <a href="https://o-yate.com">torching</a> the crust. But you can&rsquo;t just throw some bulbs in and hope for the best. You need a tight feedback loop. We use fast-response thermocouples and PID controllers to keep things under control. If your controller is slow, you&rsquo;ll overshoot your temp and end up with dry meat. That&rsquo;s why we use a pulsed-width modulation (PWM) approach. It basically lets you hover at a precise holding temperature, keeping the food warm without continuing to cook it. Now, if you&rsquo;re planning to build this or retrofit an oven, there are a few things that can go sideways. First, these bulbs get<strong>hot</strong>. Really hot. Your oven housing needs to be built for that kind of thermal load. And be careful with your reflectors. If they&rsquo;re off by even a few degrees, you&rsquo;ll get hot spots that sear the meat unevenly. Also, please—for the love of everything—don&rsquo;t use standard PVC wiring. It&rsquo;ll melt. Use high-temp lead wires. And one last thing: check your power supply. Those bulbs pull a lot of juice when they first fire up. Give them some breathing room, too. If they&rsquo;re cramped, they&rsquo;ll overheat and burn out way faster than they should.</p>
