A few inquiries have landed landed in the inbox recently about specs or where to buy those crosses(asadores) that one can can use to roast a whole lamb, suckling pig, or ribs. I’ll cover the topic of cooking with one in detail at some point, but for now, here is a little info for those interested.
Here’s a site that sells them in Argentina but I don’t know if they’ll take international orders. They have some photos of the different types–too small for great detail–and height/width measurements.
In my opinion, have one built locally at a metal shop. You’ll be paying an arm and a leg to ship something that is quite simple in design. To create one at its simplest form, all you need to do is have a couple pieces of flat iron bars wielded together. For an adjustable one, they can figure something out.
Finally, I came across this site that has some great pics of a rectangular one in action.
