There doesn’t seem to be any history to speak of with this recipe, it seems it is just a way to use up the turkey carcass after Christmas or Thanksgiving, perhaps conceived by Jane Grigson herself. In my case, it was a way of using the huge amount of turkey stock I had in the freezer from the boiled turkey recipe. We don’t like waste here in Grigson Towers, so any way of putting any leftovers such as cooking liquors and carcasses are well-received.
It does use some nice wintertime ingredients: hazelnuts are usually in good supply along with the brazils, walnuts and almonds; there’s the fine herb chervil which I have tried and failed to grow myself. They’re a hardy plant and good for growing in autumn and winter. Unless it is me attempting cultivation. It is obviously in season now as I have seen them twice for sale over the last months or so.
Bring 1 ½ pints of turkey stock to a boil with 8 ounces of raw minced turkey breast. Let it simmer for 3 or 4 minutes. Liquidise the soup and pass it through a sieve back into the pan after you have rinsed it. Jane does not mention what to do with all that turkey breast that won’t pass through the sieve – and there was plenty of it. It seemed a waste so I put some back in as it was still nice and tender.
