When I make hamburgers, I like to make them from scratch. I usually buy a tri-tip roast or top round, and chop it in my food processor. My Beloved likes to eat the first bit raw; I don't trust hamburger chopped by someone else for raw consumption so I do it myself to be sure it's fresh. He'd probably prefer eating his entire burger raw, for that matter, but he restrains his cannibalistic tendencies while I cook the burgers.
So, here's the masterpiece: Chilebrown's buns, freshly chopped and seared burger, a big slice of ripe tomato, some sautéed mushrooms, a dab of mayo and a frill of lettuce.
Holy Cow, that's good!
