It’s important to condition your cutting boards after use to keep it from drying out. Even more important if you have a wood cookstove, like I do. Wood burning fireplaces dry out wooden cutting boards and utensils, like they do wooden furniture and musical instruments.
The easiest way to condition your wooden cutting board is to wipe it with organic coconut oil, palm oil, or tallow. These saturated fats replenish thirsty wooden tools. They are antimicrobial and are absorbed deeply into the wood to keep the wood supple. They work for leather, too. Simply apply the oil generously to the surface. Wait for 5 to 20 minutes, while it absorbs, depending on how porous the wood is. Wipe off the excess. Buff the finish till it shines.
Apply the oil each time you wash your cutting boards. It will cause the wood to darken into a nice, golden patina.
For a little more longevity make a batch of this food-safe wood finish.
In less than 20 minutes it will be ready to use. I use this food safe wood finish to condition wooden spoons, wooden cutting boards, kraut pounders, spurtles, and even my granddaughters’ captive ring baby rattles. It’s nontoxic and real-food based rather than petroleum based like mineral oil.
Apply the finish to your cutting boards and wooden tools each time you wash them in soapy water, at first. After a few applications the wood won’t require it as often. It will reach saturation. You’ll notice when you reach this point because the wooden tool feels smooth rather than dry and coarse grained. It darkens the wood, bringing out the wood grain pattern, too. With its refreshing orange fragrance, it cleans as well as conditions.
