Well, I have two new words to add to my vocab. What about you Caribbean girl? It's the first time I am seeing any of these words in relation to oranges and tangerines. This forum keeps reminding me I am not as knowledgeable as I thought. Anyway, I have found tangerines more consistent on taste. I've had some oranges that could be mistaken for limes so I am going with tangerines.
I have never heard of kumquat or satsuma either. Glad I am not the only one. So, I have learnt something new. Tangerines may be more consistent on taste, but when you get an acid tangerine, it is really acid. The sweet ones are usually very sweet. I have found them to spoil quicker than oranges too.
