After reading the other reviews, I made a few changes. I doubled the orange marmalade, and also used olive oil instead of butter. While there still wasn't a strong orange flavour, it was detectable and a very tasty pork meal. A definite make again.

We couldn't taste the orange flavor either.

This was a really delish marinade! The only reason I didn't give it five stars, was because it didn't really live up to its name ~ the marinade wasn't orange-y enough at all. In fact, my husband didn't know it had marmalade or the oj in it until I told him. That aside...the marinade made for a really tasty and tender tenderloin. It was not salty at all (compared to all the other marinades I've made). A hint here, for easier blending of the ingredients: melt the butter, then add the honey and marmalade, stir with the spoon you used for the honey...and it will slide right off the spoon ~ not sticky and no waste =^.^= ~ then add to remaining ingredients. I also covered it with foil for the first 15 minutes or so, uncovering it during the final 5-10 minutes.
