A Mandarin is Citrus Reticulata. A Tangerine is Citrus Tangerina. A Satsuma is Citrus Unshiu, and a Clementine is a hybrid involving Mandarin, Pomelo and Sweet Orange.

Of these in my view the Tangerine has the distinctive and the best flavour.

As far as burgers go, in mine I put some garlic, onion, diced capsicum, a little chopped chili and a pinch of cumin powder, and ground black pepper. But if you don't have time to make your own, I recommend ALDI Wagyu burgers.
