Castagnaccio
- Tuscan Chestnut Flour Cake
Today
I'm going to take you on a trip to Italy. Tuscany, to be precise.
The
Italian regions of Tuscany, Piedmont, Liguria and Emilia-Romagna are
very rich in sweet chestnuts.
So,
ironically, chestnut flour used to be a cheap staple for people
there, while today it is one of the fancier and quite expensive
naturally gluten free flours which celiacs use.
If
you ever have tried roasted sweet chestnuts, you know the sweet
flavour of the creamy-white flesh.
Sweet
chestnuts contain very little fat, about the same amount of
carbohydrates as wheat and rice, twice as much starch as potatoes and
about 8% of various sugars which is the reason for their natural
sweetness.
You'd
expect me to tell you that I ate this cake in Italy one day and fell
in love with it, but truth to be told, I never ate it before I
actually made this one the other day.
I
love to write - about food, about science, about nearly everything on
the earth that catches my interest. And I love to write fantasy.
My
favourite hobby (besides eating and drinking coffee) is to write an
ongoing story which I started when I was twelve years old and which
most probably will continue till I watch the grass from six feet
under.
The
heroine of this story grew up with me and I grew up with her, and as
things go, we will get old together and share a place in a retirement
home one day. She's my counterpart and represents everything that I'm
not; and everything that I can't experience myself - like visiting
the Otherworld or San Casciano in Val di Pesa - I experience through
her.
In
one chapter, I went on a trip with her to see Florence, which in
reality I haven't seen yet. And discovering the Tuscan cuisine, she
had this chestnut cake and liked it a lot.
My
husband, who keeps reading the story as it grows, kept nagging that he wanted to try the cake in real life, so I purchased a bag
of chestnut flour and got to work.
If
you expect your normal piece of cake, you'll be terribly
disappointed.
Castagnaccio
is nothing like any dessert cake I have ever tried, but I did
love it.
The
consistency is slightly gummy, which at first bite might be weird.
I'm really picky when it comes to weird food consistencies, but I got
used to this after only three bites, and then I just concentrated on
the unusual, yet pleasant flavour that exploded on my tongue.
It's
not really sweet, because the only sweetness comes from the chestnut
flour, which is slightly sweet itself, and the raisins.
So
you can either eat it with ricotta or a piece of parmesan cheese, if
you eat cow's milk produce, or pecorino cheese, which is like
parmesan but made from sheep's milk, or you drizzle some good honey
over it. Preferably chestnut honey, but any other will do fine, too.
Usually,
the cake is served with a glass of wine like Beaujolais Nouveau or
dessert wine like Vin Santo.
I've
tried it with both, pecorino and honey, and I loved both. (I didn't
have the wine with it, though, as I'm not fond of sweet wine. Coffee
does the trick, too.)
If
you're open for different flavour experiences and want some real
Italian dolce vita in
the middle of a busy week or on a lazy Sunday, try this recipe, it
really has extended my culinary horizon.
Ingredients:
1
1/8 pounds (500g) chestnut flour
3
cups water
6
tablespoons olive oil
3
1/2 ounces (100g) roughly chopped walnuts
3
1/2 ounces (100g) pine nuts
3
ounces (80g) raisins
1
fresh sprig rosemary
1
pinch fine salt
Preparation:
Soak
the raisins in hot water.
Preheat
oven to 390°F (200°C)
Sift
the chestnut flour into a large bowl - don't skip this step, the
cake will not turn out well if the flour is clumpy!
Add
a generous pinch of fine salt to the flour.
Using
a wire whisk, slowly add the water to the flour, whisking
constantly, until you have a very liquid, even batter.
Drain
the raisins and add about 3/4 of them to the batter, reserve the
rest.
Add
about 3/4 of the pine nuts and chopped walnuts to the batter, too.
Grease
a 15 3/4 inch (40cm) pie pan (I only had a 13 inch pan and it still
worked - but I guess 15 inches would be better; the batter should be
only 3/8 inches (1cm) high when spread in the pan)
Pour
the batter into the pan.
Drizzle
4 tablespoons of the olive oil over the surface of the cake and try
to cover it as completely as possible.
Sprinkle
rosemary leaves from the fresh sprig, reserved raisins, pine nuts
and walnuts on top and drizzle with the remaining 2 tablespoons
olive oil.
Put
on the middle rack of the oven and bake for about 30 minutes or
until the surface has the appearance of a cracked crust and is
golden brown.
Let
cool and serve with honey drizzled over it, or with ricotta, parmesan
or pecorino cheese.
Enjoy!
Have
you ever tried hot roasted sweet chestnuts?
