On
Smoking & Wood from Down under's favorite
barby boy, BBQ Blue.
Natural Australian hardwoods can be used to add fat-free flavour to
anything from an eggplant to an eye fillet - but only if the right
amount of smoke from the right wood is used in the right manner.
THE RIGHT AMOUNT OF SMOKE
Smoke should be used like a condiment and treated with respect.
You wouldn’t think of covering a steak with an inch thick
crust of salt or pepper would you?
Well,
smoke is exactly the same - a little bit can give a big flavour
boost to whatever is being barbecued but too much can completely
overwhelm any natural flavours. Carried to extremes, it can even
impart a strong
cresote taste.
What you want to achieve is a gentle plume of sweet-smelling smoke
- not a dense cloud full of acrid-fumed fall out.
THE
RIGHT WOOD
There are a lot of Australian timbers you would not want to have
anywhere near food and some of these are listed in the fuels section.
Make absolutely
no mistake - use the wrong wood and the consequences can range
from having to throw the food away to becoming very ill.
As
a general rule of thumb:
Avoid resinous woods such as pine or cedar as they can make food
taste absolutely awful.
Never use treated hard and soft woods. The letters CCA, which
refer to a common treatment process, actually stand for Copper,
Chrome
and Arsenic. The treatment is designed to repel insects and stop
decay
- not to add flavour to food.
Stay right away from previously painted or coated timber. It
wasn't really that long ago (at least by Blue standards) when
lead was
used in house paint and some paints still contain some rather
scary heavy
metals and potentially toxic solvents.
If
you want to use wood as your primary heat source, it is absolutely
vital that you know what
type of tree the timber was cut from
and that it is completely free of any harmful chemicals. And,
for most
of us
city dwellers, that is a pretty big ask.
To
get the flavour of wood smoke without the risks, I strongly recommend
that you stick
to using commercially produced wood
chips teamed with
charcoal or LPG heat sources. Not only are they safe to use
but they are also cut from special aromatic timber.
And
I'm not talking about the wood chips sold cheaply in big bags by
nurseries
and hardware outlets. They usually
contain
pine bark
and
are best used where they are intended - on garden beds.
Organic
arsenic occurs naturally in foods such as shellfish and, in minute
amounts, is necessary for good health. The
ones that
Blue is
moaning about are the inorganic ones. I vaguely remember
reading somewhere that the Queen Mother took some sort
of organic arsenic
preparation
for many years - and I thought it was the gin that kept
her going! - Mrs Blue
Personal
preference and the type of food being barbecued will dictate your
choice of commercial wood
chip varieties. Delicate
foods are best flavoured with smoke from mild woods like apple.
However,
when I barbecue fish or shellfish, I often use a handful of fresh
green
herbs
(rosemary
and thyme are good ) or a few bay leaves torn from
the garden and simply tossed on to the coals.
Robust
woods such as hickory, pecan and mesquite are popular choices for
adding flavour
to beef, pork and lamb.
Hickory
and its very close cousin pecan are the perfect all-rounders. My
particular preference is for pecan
as its flavour has
greater depth and seems a little more mellow
than hickory. However,
the two are so
similar that one is often sold as the other.
I have it on good authority that most ‘genuine hickory’ axe
handles sold in Australia are, in fact, pecan.
THE RIGHT MANNER
Smoke is what you want and soot is what you don't want. A disgusting,
foul-tasting layer of soot on your food shows
that the wood you added to the barby flamed rather than smoked.
You've
got to slow things down so that the wood chips quietly smoulder away
and progressively release the smoke
scent. The big thing
to remember is to never use dry chips. Always
soak them in water for
at least an
hour - but overnight is better.
Most
of the actual take-up of the smoke flavour happens early in the cooking
process when the
food contains
maximum moisture.
That's
why
I usually wait for the wood to start smoking
before I place the food on the barby.
