Big 10 quart Club aluminum roaster with well-fitting lid, 18 1/2" across the handles. Holds more than 2 gallons comfortably.
You could fit two chickens in here, or a beef brisket larger than anyone can afford, or an old-fashioned turkey (a small turkey by today's standards, or a free range bird).
This is the brown colored exterior, plain aluminum inside. It's been used but pretty well cared for - it's clean but does show wear and scratching. Bottom is nice and flat.
