CHESTNUT CHEESECAKE

_Editor's note: The recipe and introductory text below are from_ [Feast: Food to Celebrate Life](http://astore.amazon.com/epistore-20/detail/1401301363), _by Nigella Lawson._ There is no doubt about it, anything with chestnuts in it, even if they come vacuum-packed or canned and are perennially available, is so right for this time of year. This hums the tune, but in a subtler key. The chestnuts are present, in the form of a gritty, grainy sweetened purée: some to add to the cookie base; some to fold through the plain cheesecake filling before baking; and yet more - well, it is Christmas - to drip in a thick syrup over the cake when served. And yet, you know, the chestnuttiness is not blaring: there is something undeniably festive about this, but not in a full-on, party hat kind of a way. As with all cheesecakes, you need to bake this the day before you want to serve it.

Ingredients

4 ounces (2 cups) Graham cracker crumbs
1/2 stick butter
1 heaped tablespoon sweetened chestnut purée
2 cups cream cheese
3/4 cup superfine sugar
3 eggs
3 egg yolks
3/4 cup sour cream
1 teaspoon lime juice
1 teaspoon vanilla extract
1-2 tablespoons rum
1 cup sweetened chestnut purée
1/3 cup water
1/4 cup rum
1 tablespoon sweetened chestnut purée
1/4 cup superfine sugar
1 tablespoon butter

Steps:

Preheat the oven to 350°F, and put the kettle on to boil.
For the base, process the crackers, butter and heaped tablespoon chestnut purée until like fine crumbs. Press the mixture into the bottom of a 9 inch springform pan and place in the fridge while you make the filling.
Beat the cream cheese until smooth and add the sugar. Add the eggs and egg yolks, beating them in one by one until they are incorporated into the cream cheese and sugar. Pour in the sour cream, lime juice, vanilla extract and rum, and beat again until smooth and creamy. Finally fold in the sweetened chestnut purée. Don't worry about making a fully amalgamated mixture: smooth cream cheese with grainy streaks of chestnut is just fine.
Line the outside of the springform pan containing the crumb base with a good wrapping of plastic wrap, so that the whole of the bottom and sides are enveloped in plastic. Do the same with aluminum foil, covering the layer of plastic wrap to make a very watertight casing. Stand the springform, thus covered, in a roasting pan and pour in the chestnut filling. Once that's done, pour water from a recently boiled kettle into the roasting pan to come just over an inch up the side of the pan (the plastic wrap will make it bob up and down a bit) and place in the oven to cook for an hour.
When the cheesecake's ready it should be just set on top with a hint of wobble underneath; it certainly carries on cooking as it cools. Take the cheesecake out of the roasting pan, take off the foil and plastic wrap and let the cheesecake cool on a rack. Refrigerate overnight before unmolding and leaving it to get back to room temperature. If you need to unmold it long before you want to eat it (I often do just because I like to get all bothersome stuff out of the way before people arrive) then just sit it on its serving plate in the fridge until about 20-30 minutes before you want to eat it. I'd take it out as you sit down to dinner or lunch or whatever.
You can make the syrup in advance but do not pour over until the actual point of serving.
You just put all of the syrup ingredients into a saucepan and melt together. Let the syrup boil for 10 minutes, then cool to just warmish (or even room temperature) before criss-crossing the top of the cheesecake with it.
