What wood-fire cooking actually changes in a kitchen
When the gas range at Fervores was replaced by a sandstone hearth in the spring of 2018, the change was not cosmetic. It altered what could be cooked, how long it took, and what the kitchen smelled like at 22:00 on a Friday. This is a practical account of what that shift involved.
Why encina wood specifically
Encina is the Spanish holm oak, and it burns long, hot, and with very little smoke once it reaches temperature. It is the same wood used in the dehesa landscapes of Extremadura and Andalusia to feed the pigs that become jamon iberico. There is a logic to using it in the kitchen: the same terroir that flavours the meat also flavours the fire that cooks it.
The alternative most wood-fire kitchens use is olive wood, which is abundant in Andalusia and burns well. But olive wood gives off a slightly resinous smoke that can be overpowering on delicate vegetables or fish. Encina is cleaner. It lets the ingredient speak rather than adding its own character.
Reading temperature without a dial
A gas range gives you a number. A wood hearth gives you a colour, a sound, and a feeling on the back of your hand held at grate level. Learning to cook on it takes longer than learning to cook on gas, and the first winter at Fervores involved a fair amount of food that was either underdone or charred past usefulness.
The practical skill is managing the bed of coals rather than the flame. A high flame is for searing and for bread. A deep bed of grey-edged coals is for slow cooking, for fish, for vegetables that need time. The transition between the two takes about forty minutes, which means planning the evening's service around the fire rather than the other way around.
What it does to the menu
The hearth narrowed the menu. Some dishes that worked on gas do not work over fire, either because they require precise low temperatures or because they involve sauces that need constant stirring. The kitchen stopped making those dishes. The menu became shorter and more focused on things that benefit from smoke and char: vegetables, fish, pork cuts that can take a long rest over indirect heat.
It also changed the sourcing. When the cooking method is simple, the ingredient has nowhere to hide. The tomatoes in the gazpacho matter more when the gazpacho is just tomatoes, oil, vinegar, and water. The goat's cheese from the Alpujarras matters more when it is placed directly on the grate with nothing added.
The hearth is not a statement about authenticity or tradition. It is a practical tool that produces a particular kind of food. Whether that food is what you are looking for is something you can only find out by sitting down to it.
