Whoa! I'm not sure I've ever seen one that looks like this! I've seen culotte called honeymoon roast/steak. This looks like it's got rib meat wrapped around a clod heart. Weird. I bet it's good though.
I never have heard of it till a few months ago, but this doesn't look like the ones i've seen on video's. the ones I've seen are more flat.
The fatty part in the lower section of photo looks like a boneless plate, but what the heck is the lean part above? It all looks like two separate pieces that don't belong together. Could that be a brisket and plate boned and tied together? But brisket normally isn't marbled like that, especially at the 9 O'clock point of the photo. It could be a small end ribeye with a boneless plate tied to it. But those two things shouldn't be cooked together. I'd really like to see it from a better angle (directly above). Can't figure out why it would be called honeymoon. Don't really think plate meat belongs on a roast unless its a pot roast. The lean center part almost looks like eye of round except for that fat at 9 O'clock position.
i looked it up and it said honeymoon roast was a sirloin cap that aint no sirloin cap
I don't have any idea what the lean part is. If I had it in hand, I think I'd know for sure. I'm almost positive the fatty part is from a boned out plate. The area that would be spareribs on pork. You don't really see those anymore unless you're breaking beef.
A question for mimeatguy, I noticed on the photo that you have a smoke oven. Please tell us what goodies you make and smoke, with some instructions on curing and smoking times and temperatures. Best regards from Australia. Jan.
