Food safe finish

Recommended Posts

Given the current climate, we can't get tortillas so one item on my honey do list just got bumped up a ways, making a tortilla press. It was at the "meh, if you ever get to it" position on the list, now it's near the top since I think I have all the material I need. What I don't have is some food safe finish to coat it with.  I'm not going to go out to buy anything so I have to work with what I have.  That consists of various oil and water based polyurethane and some spar urethane.  I could probably put some mineral oil on it, or just leave it bare for now and use some wax paper or silicone baking mats temporarily until I can get something appropriate.   If the latter, any suggestions?

Mineral oil or nothing, for now. Maybe salad bowl finish later. I wouldn't use any film finish that might lift away from heat / moisture and flake off into the dough.

2 pieces of parchment paper, a counter top, a plate and body weight makes a fine tortilla press. 

Pssst! It’s his way of getting out of the house for a few hours! 

A piece of wax paper or as Bryan suggested, parchment paper, on top and bottom of the dough.

Will mineral oil cause problems with the finish later? https://generalfinishes.com/wood-finishes-retail/oil-based-topcoats/oil-based-wood-bowl-finish It says it's oil based so I'm guessing no, since they're both oils, but pretty new to finishing so all the conflicts and interactions are a mystery to me. I'm reading Understanding Wood Finishing by Bob Flexner so I'm getting there, but only on chapter 2 at this point.

Thanks Coop. Yeah, saving time is not the goal here.  In fact we made some the other night with a rolling pin, just looking for something unique to do.

I think if you start with mineral oil, stay with it. It takes a loooooooong time for it to 'dry out' enough to be comfortable with a curing finish over it.

I agree. Go with mineral oil. It looks best before you use it for the first time. After washing the finish will dull. But so what. It will be a good tool that will last a very long time. And at any time you can freshen up the finish. Then wash it again...Because of washing think of it as a tool, not a display piece. Now you owe me a taco...

Almost all wood finishes are food safe when they are fully cured.

That being said, my favorite finish for food items is a mixture of beeswax and mineral oil. Leaves a fantastic feel, and smells like beeswax! I often use it as a regular wax now over other finishes.
