A friend of mine was shocked that the pasteurization process leaves orange juice flavorless and that scent and flavor particular to a brand of orange juice is later added. Subsequently, he has sworn the stuff off. I have no problem with people having "revelations" about food, but it does bug me that my friends who grew up in the US really expect that their food is as wholesome as has been advertised, especially when the basics of advertising are well understood.
This is why I purchase frozen concentrate.
You are probably right, or close to being correct about that stuff. I should do some research on that. All I know is that to me, frozen concentrate tastes better than orange "juice" that costs the equivalent price per gallon.
Well, I'd say it's distinct from both because it includes the peel and has a very distinct flavor whereas between jelly and jam the biggest difference is texture. But closer to jam, since jellies usually just use juice. You could theoretically press citrus peels, but I just buy the stuff online. You can get cold pressed oil from all kinds of varieties of citrus for pretty cheap (a few dollars per ounce, a ton of servings considering how strong the stuff is) if you look around a bit.
