I think I would prefer a mandarin purely because they are so easy to eat and I can eat one while watching tV after dinner.
With an orange, although I probably like the taste of these more, I have to eat this over the sink as it makes a mess, so I guess I would rather eat a mandarin even though an orange is juicier and often sweeter.
Mmm, that's a hard one because I love mandarins but only if they are sweet. Then again, there is little I find more refreshing than biting into quarters of oranges. Wouldn't it be great if there was a manderine and orange cross. I think a tangerine is pretty close but for some reason I don;t like them at all.
I have no preference. I like mandarins for their convenience - ready made "enclosed" segments with a peel which is removed easily (and free because we own a dwarf mandarin tree!). I enjoy oranges for their juicy flavour.
(my husband loves tangelos!)
I can never manage mandarins. My mother used to set mandarin segments in orange jelly . . . . put me off for life. I just whack an orange into 4, then 8 and sometimes 16 segments and slip it off the skin like butter. It takes me half the time. I find the seeds and strings in a mandarin are a real battle.
