These cookies are definitely good enough to be worth showing the world how inept a welder I am.
Dorie Greenspan has been making these amazing looking "Jammer" cookies for a while. We've never tried making them. This presented a perfect excuse for me to try to improve my completely awful welding skills. Here's how I made a set of 3" and 3.5" cookie rings. I made them at techshop.
Step 1: Cut some strips
Cut a sheet of stainless steel to 9.7" (3" * π plus enough overlap for the ring to stay together) long, then cut it the other way into 1.5" strips. I used a hydraulic sheer.
