First stage of the process was make a custard - 568ml of cream (yikes, low cal then) brought to just below boiling with 300ml of whole milk and a split vanilla pod. This was then poured onto 6 egg yolks which had been whisked with 50g of caster sugar. Then the mixture was returned to the saucepan and stirred until it thickened slightly. When it was cold enough I put it in the fridge and left it alone until the next day.
Then, I fired up the ice cream machine (not the quatro). It's only one of those that you keep in the freezer, but it's quite effective. It just churns the mixture with a plastic paddle and gets colder and thicker as ice crystals form. I would like one of those big ones that are always good to go but I just don't I think I'd use it that often and they're just such a big bit of kit to store.
The base vanilla was then squirreled away to firm up a tad more before being 'rippled' with 300g of pureed and sweetened raspberries. Something to note here - when ice cream freezes it always tastes less sweet than when it was in it's unfrozen state, so you have to add more icing sugar than you think to the soft fruit.
I think this looks like something 'Dexter' would keep in his freezer
I have to say that it was really worth the effort. I've only ever had commercial raspberry ripple and this knocked spots off it. It was creamy (obviously as it was virtually all cream!) and the rippled parts were really raspberryish and tangy and yummy.
