Hmm, just tried Nigella's Yellow Squash Soup of Happiness, and I'm a bit disappointed. The turmeric is a bit overpowering for my taste, but that's easily fixed. Something not so easily fixed is that in order to cook to rice you basically need to boil away the chicken stock, and you're left with more of a thick sludge than a soup. And it does not feed 4. Has potential, though. Reduce the turmeric, add another yellow squash, maybe some chicken, and then serve over a good helping of sticky rice, could be quite nice.
