Tart tangerines <puckered up face emoticon> - what can I do with em?

[OliviaMumsnet]

I was suckered into buy one get one free tangerines last week at the supermarket and they're really sour - almost too sour to eat/
Anyone got any clever ideas of what I can do with them?
TIA

Nigella's Clementine cake? (Unless I'm being particularly stupid and you can only use clementines - I'm not exactly sure of the difference between those and tangerines!)

Oooh that sounds good, will have a look for it.

Second the clementine cake - it is fab

Did you find it, Olivia? If not, I'm sure I have the recipe somewhere and I'll dig it out for you.

flambe them in caramel and rum
