F.&R.Dahl: "This delicate soup, popular 100 years ago, is now unusual. On no account should it be liquidized at any stage, as that ruins the texture"
Mince the almonds and, using a pestle and mortar, reduce to a paste with the egg yolks and a little stock, to stop them oiling.
Bring the stock up to simmering point in a saucepan and whisk in the beurre manie. When that has dissolved, whisk in the almond paste.
Cook gently for 30 minutes.
Strain through a sieve, add the cream, season with salt and pepper, heat gently and serve.
