It's an easy to cook recipe of soup - with a warm and tantalizing taste. It is described as the best recipe of an Estonian woman who had moved all over Europe during World War II. Flecked with splashes of heavy cream and touched up with a few scallion slices, it's a pretty soup - with a hot earthy sweetness overlaid with the tart of lemon and the spice of curry. Absolutely outstanding as a first course to spicy barbequed chicken or pork.
