well - maybe not - it's cold and rainy
but barbecuing altoids tins doesn't require perfect weather
(don't do this indoors in your home oven due to paint fumes)
how I did it:
clean your tins
remove lids if you want to
wrap tins in a foil packet - loosely packed but sealed shut
barbecue on high (about 475 degrees) for about 15 minutes
let cool
unwrap (do your unwrapping outdoors due to the captured paint fumes in the packet)
it's an imperfect process with unpredictable results
some of these I will be bbq'ing a second time
I LOVE the tin on the left in the above picture - and have no idea why it came out so great
anyway - have fun with this - isn't that the whole point of a barbecue?
