Curing of New Racks in TEFS

post #1 of 5
Thread Starter 
Hey all.

Just want to be sure I'm squaring these things away...

So today I spent $70 on some 3/4" expanded steel and some 1/2" x 1/2" angle to make some better more supportive racks. They are made out of cold rolled steel (SS was way too pricy) I cut and welded them now on to the "curing".

I washed real good with a heavy brush and dish soap, dried and sprayed with canola oil, placed in the TEFS at 325* for 1/2 this enough to cure these, rendering them safe to use?

I made three at 24" D x 18" W...these should work very well!

Thanks for the compliments on my racks....But does anyone know if what I mentioned above is enough to "cure" the cold-rolled steel?

It works for cast iron so it should work for those racks.  Although I would run them at temp for at least an hour.  That's the general rule on re-seasoning cast iron that has been over cleaned (ie, dish soap & scrubbing used).  You could let them run longer, but let them cool slowly in the smoker when done.  


There has been quite a few posts about seasoning cast iron lately and apparently Flaxseed oil from the health food store is better to season with than cooking oil.  Reported to leave less of a sticky coating and more of a hard carbon coating than cooking or spray oil.


Nice job on the racks & the smoker!!!




Just found this article from Cooks Illustrated.  They even did a torture test of two pans after seasoning by running them through a cycle in the dishwasher to compare flaxseed oil seasoning vs veggie oil seasoning.  The flaxseed oil pan was still seasoned and the veggie oil pan was stripped back to unseasoned cast iron (photos below).


So it's official. Flaxseed oil is the best way to go....




We'd seasoned our cast iron the same way for years. But when we heard about a new method that creates a slick surface so indestructible that touch-ups are almost never necessary, we were intrigued.


For years we’ve seasoned cast-iron cookware in the test kitchen by placing it over medium heat and wiping out the pan with coats of vegetable oil until its surface turns dark and shiny. When a pan starts to look patchy, we simply repeat the process. But when we heard about a new method that creates a slick surface so indestructible that touch-ups are almost never necessary, we were intrigued. Developed by blogger Sheryl Canter, the approach calls for treating the pan with multiple coats of flaxseed oil between hour-long stints in the oven.

We carried out Canter’s approach on new, unseasoned cast-iron skillets and compared them with pans treated with vegetable oil—and the results amazed us. The flaxseed oil so effectively bonded to the skillets, forming a sheer, stick-resistant veneer, that even a run through our commercial dishwasher with a squirt of degreaser left them totally unscathed. But the vegetable oil-treated skillets showed rusty spots and patchiness when they emerged from the dishwasher, requiring reseasoning before use.


Why did the new treatment work so well? Flaxseed oil is the food-grade equivalent of linseed oil, used by artists to give their paintings a hard, polished finish, and it boasts six times the amount of omega-3 fatty acids as vegetable oil. Over prolonged exposure to high heat, these fatty acids combine to form a strong, solid matrix that polymerizes to the pan’s surface.

Although lengthy, seasoning with flaxseed oil is a mainly hands-off undertaking. We highly recommend the treatment:


1. Warm an unseasoned pan (either new or stripped of seasoning*) for 15 minutes in a 200-degree oven to open its pores.


2. Remove the pan from the oven. Place 1 tablespoon flaxseed oil in the pan and, using tongs, rub the oil into the surface with paper towels. With fresh paper towels, thoroughly wipe out the pan to remove excess oil.


3. Place the oiled pan upside down in a cold oven, then set the oven to its maximum baking temperature. Once the oven reaches its maximum temperature, heat the pan for one hour. Turn off the oven; cool the pan in the oven for at least two hours.


4. Repeat the process five more times, or until the pan develops a dark, semi-matte surface.


*To strip a cast-iron pan of seasoning, spray it with oven cleaner, wait 30 minutes, wash with soapy water, and thoroughly wipe with paper towels.


Even after a run in the dishwasher, the pan seasoned with flaxseed oil held on to its perfect seasoning. The pan seasoned with vegetable oil did not.
