Seems like cutting boards are on everyone’s minds these days. Probably because we are all making holiday gifts. Either way, this is the time of year you can expect almost one forum post a day asking a question about cutting board finishes or “food safe” finishes. And the responses to these posts are nearly always the same: Person 1- The best finish for a butcher block is mineral oil. Person 2- NEVER use varnish or salad bowl finish on a cutting board! What are you, stupid?!?! Person 3- Mineral oil and wax are the best! Person 4- This person usually provides a bunch of extra information that you didn’t ask for. Ok so I am generalizing here for fun, but you get the picture. I have noticed as well that many of the people posing these questions may be doing so because of my advice from Episode 7- A Cut Above. To sum up, I said that my favorite finish for end grain butcher blocks is salad bowl finish (aka varnish). But remember my caveat. I said we are NOT trying to build a film. And that’s exactly what the folks in the forums are trying to say. If you build a film, the film will then be cut by a knife. The cut will allow moisture to seep under the finish and become a wonderful home for all kinds of bacteria. I can’t disagree there. But with my method, you never actually build an appreciable film. I recommend diluting the finish sufficiently so that it immediately gets absorbed into the wood’s wide open pores. Think of it like a vertical bunch of straws that you are filling up with finish. Within a minute or two, you will notice that finish is actually seeping out of the bottom of the board. This is exactly what we want. At this point, I usually set board on its side and allow it to dry overnight. I do this 3-4 times with a light sanding in between each session. By the final coat, you should start noticing that the finish doesn’t really absorb any more. You are now starting to develop a film. One last wipe with a clean cloth and call it DONE.
