Live fire cooking is cooking with an open flame — wood or charcoal, not gas or electric — where the cook controls the heat through the fire itself rather than a dial or thermostat. It is the oldest form of cooking, and for a growing community of outdoor cooks in the UK, it is the only form worth pursuing seriously.
What Makes It Different
The difference isn’t just the fuel. It’s the relationship between the cook and the heat source.
With gas or electric, you set a temperature and the equipment maintains it. Decisions happen before and after the heat, but the heat itself is automated. With live fire, the cook is part of the system. You build the fire, manage it through the cook, read its state continuously, and adjust in real time. There is no set-and-forget. There is only cook.
This demands more. It also produces more. Smoke from burning hardwood creates flavour compounds — guaiacol, syringol, and related phenols — that gas cannot produce. The Maillard reaction on live fire occurs in the presence of smoke as well as heat, which changes the crust and character of meat in ways that controlled cooking cannot replicate. The flavour difference is real and measurable.
The Core Techniques
Direct Heat
Food sits directly above the coals or flame. High heat, fast cooking. Used for steaks, chops, fish, skewers — anything that benefits from a hard sear and a short cook time. Direct heat requires a good coal bed: even, hot, producing consistent radiant heat rather than active flame. Flame causes charring, not cooking.
Indirect Heat
Food sits beside the heat source, not above it. Coals on one side; food on the other. The lid or enclosure traps heat and creates a convection environment. Used for large cuts — brisket, whole chicken, racks of ribs — anything that needs time to cook through without burning the surface. Indirect cooking with live fire is where smoke flavour develops most fully.
Two-Zone Cooking
A practical combination: one side of the grill runs hot for searing; the other runs cooler for finishing. Sear a steak directly over coals, then move it to indirect heat to rest and come to temperature without burning. Two-zone is the most versatile live-fire method and the default setup for experienced cooks handling anything beyond simple quick cooks.
The Reverse Sear
Counterintuitively, starting with indirect heat and finishing with a direct sear produces better results for thick cuts than the traditional sear-first approach. The protein heats more evenly during the slow phase; the final sear is fast, controlled, and produces a better crust. Reverse sear requires two-zone setup and confident heat reading — it rewards the cook who has learned to read the fire.
Reading the Fire
The central skill of live fire cooking is reading the fire. This cannot be reduced to a temperature number — it’s a pattern of observation built over time and sessions.
A good coal bed glows orange-grey with minimal active flame and produces even radiant heat. Too much active flame means the fire is too young — let it settle before cooking. Coals that are pale grey and no longer producing heat are exhausted — add fuel or move the cook. Wind changes the fire state; your position relative to the fire changes what it does to the food; the depth of the fuel bed determines how long the heat lasts.
None of this is mystical. It’s learned. Every session on live fire teaches you something. After a season of regular cooking, you develop intuition that no amount of reading can replicate.
The Right Kit for the Job
Live fire cooking is hard on equipment. The heat, the force, the outdoor conditions expose poor kit quickly. A thin apron offers no real protection from fat splash at grill temperature. A lightweight fork bends under a 3kg brisket. A round skewer lets food spin on the grill, destroying a long cook in a moment of inattention.
The Bison Hill range was built specifically for live-fire use:
- The Gaucho BBQ Grill Apron — 12oz denim, eight utility features, genuine protection and practicality in one piece
- The King Fork — handles 3kg without flexing, the right tool for large cuts
- The Bison Skewer — flat blade grips food and prevents spinning on the grill
- The BBQ Block — English oak, large enough for carving and serving direct from the fire
Good kit doesn’t make you a better cook. But poor kit gets in the way of good cooking. The difference between adequate and right becomes most apparent when the session is long and the fire demands full attention.
Why It Matters
Live fire cooking is one of the few activities in which the practitioner is fully present. No autopilot. No set-and-forget. The fire demands attention and returns it in the form of better food and a better experience — for the cook and for everyone eating.
The culture built around live fire — the gaucho asado, the churrasco tradition, the whole-animal events, the backyard fire pits — reflects something real about what cooking over an open flame does. It slows things down. It requires presence. It produces something worth gathering around.
Bison Hill is built around that culture. We make kit for people who take it seriously — and we think they deserve equipment made with the same seriousness.
