This recipe is courtesy of Nigella Lawson. Nigella says, "This is a cinch to make, and easy-easy-easy to eat. It is, now that I come to think of it, in effect a no-churn version of the ice cream in Forever Summer. If you want to serve it in glasses dipped in sugar and salt, by all means do. But it is so good, that even as someone is not a committed ice cream eater and no kind of a drinker, I find I can spoon it straight into my mouth from the container I've chilled it in. In other words: no decorative touches or embellishments are remotely needed. This is truly the express way to dessert-deliriousness."
