How do you roast chestnuts?
Score chestnuts by cutting a small x on the flat side with the tip of a sharp knife. Place on a tray in a hot oven or under a moderate to hot grill for 10 – 15 minutes depending on size. Parts will burn and go black, don’t worry, this is just the outer shell. When ready place nuts in a clean tea towel, wrap them for up to 5 minutes. Unwrap and peel both the outer shell and inner skin (pellicle) off.  Enjoy!
What is the difference between varieties?
Most people are not aware that there are different varieties of chestnuts. It’s probably best to think of them like potatoes. Some varieties are better for mashing, some for roasting, some for potato salad.

With chestnuts, some varieties such as Red Spanish are great for purees and soups. Others such as De Coppi Marone are best roasted because they are really easy to peel and have a smooth texture and sweet flavour. Purton’s Pride is good for peeling and serving whole in a sauce or as a vegetable accompaniment.

Most growers in the Australian industry now sell by variety, so once you get to know the varieties you can decide which one suits your needs and tastes. There are several different Chestnut varieties to choose from that suit a list of applications. See below the different varieties and their uses.

Buffalo Queen – an early season nut, better boiled than roasted
Bouche de Betizac – a large early season nut, sweet flavour, easy to peel.
Red Spanish – a large Japanese style nut, best boiled or steamed.
De Coppi Marone – mid to late season nut, the best roasting nut. easy to peel with a rich sweet flavour.
Purtons Pride – late season sweet chestnut, easy to peel. Great roasted, boiled or steamed. Versatile all-purpose nut.

What is the difference between Chestnuts and Horse Chestnuts?
The Horse Chestnut, Aesculus hippocastanum, which has also been known as Hippocastanum vulgare (Gaertn.), is an entirely different tree from the Sweet Chestnut. In fact it is not even distantly related, being a much more recent importation to English soil. It is a native of northern and central parts of Asia, from which it was introduced into England about the middle of the sixteenth century.

The name Aesculus (from esca, food) was applied originally to a species of oak, which according to Pliny, was highly prized for its acorns. How it came to be associated with the Horse Chestnut is very uncertain; perhaps, as Loudon suggests, it was given ironically, as its nuts bear a great resemblance, externally, to those of the Sweet Chestnut, but are unfit as food.

Hippocastanum (the specific name of the common sort) is a translation of the common name, which was given – Evelyn tells us – ‘from its curing horses brokenwinded and other cattle of coughs.’ Some writers think that the prefix ‘horse’ is a corruption of the Welsh “gwres”, meaning hot, fierce, or pungent, e.g. ‘Horse-chestnut’ = the bitter chestnut, in opposition to the mild, sweet chestnut.

Horse chestnuts are much smaller in size to sweet chestnuts. Juice can be extracted for some herbal medicines from both the bark and fruit of the horse chestnut.

How can I dry chestnuts?
(Using the Ezidri Snackmaker food drier)

Cut the nuts in half (a cleaver works well) and place them, cut side down on the drier trays.

Set the heat to medium and allow nuts to dry for 8 to 10 hours.

At this stage the shell will almost slip off and the pellicle (the firmly attached brown skin which encases the actual nut) can also be removed fairly easily.

Alternatively you can place the cooled nuts in a well-sealed container (or firmly closed plastic bag) and remove the skin later (family entertainment on a cold wintry evening!).

Using a conventional oven, chestnut halves should be dried on a wire rack at about 125°C for up to 10 hours. (Fan forced ovens take less time, so test for dryness after 8 hours.)

Store nuts in the pantry until needed. They will keep for up to 12 months.

When using peeled nuts, they will need first to be re-hydrated. Simply cover them with boiling water and leave overnight (for up to 12 hours). Drain off liquid and then use nuts as you would fresh ones.

Remember that the nuts are still raw at this stage and will need to be cooked for the same length of time as fresh nuts.

Boiling chestnuts is a simple method. Place in hot water for 15 to 20 minutes after which they can be pureed, sieved or chopped.

Can you freeze chestnuts? How?
Yes, Chestnuts can be frozen, two ways.

To freeze chestnuts so that they can be enjoyed all year round, leave the shells intact and pack them into a sturdy plastic bag or container. Frozen nuts once thawed are not suitable for roasting but are perfect in soups, purees and seasonings.

You can also roast chestnuts, peel and then freeze for use in stuffing’s, soups and cakes and to snack on.
