I set out butter to soften for the toasted bread and whipped up the classic burger sauce (recipe below) so it could set up and the flavors meld. After I got changed, I cooked the thin-sliced onions, buttered and toasted the sourdough slices, rolled the ground sirloin as thin as I could get it between sheets of wax paper, and I made us these:
The burger patties ended up smaller than I'd anticipated and the bread was sort of chewy, but the flavors had us all smacking our lips with glad hearts.
