Our policy has been to provide good quality food at reasonable
prices and have this cooked over open fires and barbecues. We
believe this provides the necessary atmosphere and that the high quality
of food will mean people will return for more both this time and in the
future.
Spit Roast
The centre
piece of this is the roasting of pigs and lambs on a rotating spit over
an open fire. If you haven't done this before take note of our advice
which is experience gained over many years using a variety of equipment
but note also that fires are unpredictable creatures and that all timing
in particular is flexible. When organising your cooking area it's a good
idea to place the spit near to the front so that the general public can
see it. If they can look at what they're buying we hope it will encourage
them. At least it gives them something to do if the queue gets too long!
A large supply of wood is essential to provide a depth of charcoal and
ashes for cooking at length. We have lit the fire at 4am for cooking 7-12
for a small pig but now prefer lighting at 11pm for cooking at 4 -12 for
a larger pig. In fact we now prefer charcoal, which, though it costs more,
gives a fierce heat in much less time than wood.
Lambs take less time to cook but are more susceptible to burning. Pigs,
protected by tough skin and a layer of fat, can cook endlessly in their
own juice.
If you thought spit roasting simply involved sticking a rod up a pig's
bottom, think again! Firstly the pig must be delivered, properly butchered
and cleaned out, with the skin cut diagonally along its length, as near
to the time of use as possible. We have used a refrigerated lorry as well
as cool store, but you should avoid having to keep it for more than 24
hours beforehand.
Next the pig must be prepared for roasting, which involves in our case
a long drill bit on an electric drill to drill through the spine of the
beast and place lateral fixing rods in place. These rods are essential
to allow the beast to rotate fixed firmly to the central post though locating
and fixing them on the central post can be a problem. The diagram below
drawn from above but at 45 degrees, shows the central post suspended on
tripods over two separate pits.
A pig is flexible around its hips and keeping the beast rigid requires
half a dozen lateral rods the length of the animal. Wiring up the carcase
holds it firmly and improves rotation throughout cooking if it is tightly
bound close to the pole. Too tightly wired, however, and the wire cuts
through the meat. [see equipment list and timetable in appendix]
Either pigs or lambs can be attached to the pole in the "69"
position where the carcase is nose to tail overlapping. The central pole
must of course be long enough and have enough fixing holes but it is a
generally economical use of time and equipment.
An alternative to the rather
fiddly lateral rods is a device like a clamp with spikes facing in which,
if two are mounted on the central post and screwed firmly can clamp the
carcase in place as it rotates. There can still be a problem at the hips
so at least two lateral rods are still recommended. The spike + clamps
method seems to work better with a side of beef where the basic carcase
structure is rigid.
Some people "crucify" the carcase so it can be splayed out
and wired to a central post which has two cross beams - one for the forelegs
and one for the back legs. This is quite easily wired up without the need
for groping in the dark interior of the carcase. Picture below.
A further alternative is a cage which would surround the meat and hold
it in place from the outside. We have not used this since it requires
a lot of welding and still may be inflexible as to the carcase size, but
it does have ease of use to recommend it.
A
drip tray under the meat but at a distance from the fire can be useful
for basting the meat. Pork generates enough fat to be self-basting but
lamb can benefit from the juice in the tray. The tray can also be used
to crisp up pork scratchings, which for some are a rare delicacy. If you
use two fire baskets with a space between and the pig above the fat can
drip into a drip tray laid on the ground below.
Rotating the Meat.
In ancient times there would have been man power available throughout
the night to rotate the meat by hand. Modern man usually has better things
to do with his time and so we make use of an electric motor. A pal of
ours has, however cooked a side of beef on scaffolding poles housed in
a hand made brick oven, rotating the scaffold poles every 15 minutes by
hand. So it's possible.
The picture above, taken in Stratford in about 1895, shows a wooden cartwheel
chocked into place on a long pole which may also be of wood or possibly
cast iron. The wheel would have been rotated regularly but not continuously,
while the brick walls would have retained and reflected the heat and been
quickly dismantled when the itinerant pig roaster moved on. The pig is
kept in place using double spikes on either side of the spine.

Our big engine
has a motor rotating a two inch pole inside a cage over an open
wood fire. The cage has sides to reduce heat on the operatives
and to reflect the heat back on the meat.
It can cope with a 150lb pig or two barons of beef with ease.
It has wheels running on rails so it can be removed from the heat
to cut off large chunks.
Here's John standing proudly beside it. There's another picture
above. |
| Crucified.
We recently used a piece of kit with a "crucified"
80 pound pig laid flat and wired to a cross (see below). Being
flat there was less of a problem heating it through (though the
haunches were only just done in time.)
The cross was rotated by hand for the 7 hours of cooking - one
hour for the top, one hour for the bottom, then repeat; half an
hour for the top, half an hour for the bottom, then repeat; fifteen
minutes for the top, fifteen for the bottom, then repeat; the
last hour at a higher heat to crisp it off.
It worked beautifully and evenly. |

The Little
Engine
Our little engine's motor works off mains electricity
and rotates every 10-15 seconds.
Its drive fits on to a coupling on the end of the central pole
and so can be coupled up when the beasts are set up.
The pole is supported on u-shaped cradles and the motor is protected
from the heat of the fire by a simple reflector.
Wiring up the beasts as close to the central pole as possible
and cooking two together helps balance the rotated weight and
evens out the strain on the motor. |
| The
Motor
As the motor may have to work continuously for nine hours or
so, anything which eases the load is to your advantage.
This is our original motor, right, made from a Lancaster bomber's
bomb-door motor.
You may even work a simple hand cranked alternative using dexion
for example in the event of the motor failing.
Since the aim is to cook the meat evenly, a rotation of 40 degrees
every ten minutes might be as effective as a continuous rotation.
Though rather more tiring on the operator .... The crucifix position
is probably better for hand turning as it offers more area and
less density to the heat. |
 |
| The Reflective
Box
A later adaptation to this system means we have added reflecting
walls of stainless steel to creat an oven around the rotating
pig or lamb. Less dramatic to watch, but quicker to cook.
Incidentally this picture and the one below were taken at different
Feasts. This explains why the motor enters from the left on one
and the right on the other. |
 |
| Here
you can see the reflective box opened up. The motor, connected
to an electric cable, sits outside the box and turns slowly by
means of gearing. A socket connects to a detachable fitment on
the pole. The lambs are secured to the pole by long bolts which
enter drilled holes in the animals' spines and then through holes
in the pole. The bolts are screwed tightly to the exit hole. The
carcases then rotate with the pole which rests in a cradle at
the far end.
Note that the fire basket with its charcoal have been pulled
out on rails made from metal rods in order to give access to the
meat. The meat can now be cut off in a large piece, the basket
and sides replaced for further cooking while the cut piece is
sliced elsewhere for serving. |

And here is a method I'd like to work towards.
I call it The Iron Maiden because it recalls the famous instrument
of torture where the victim is closed inside a hinged body-shaped
box with spikes on the inside. What larks, eh?
Anyway, here's a hinged oven with a hinged wire cage inside,
size matching a standard pig carcase, the whole rotating inside
the oven with a gas heat source below and to the side plus drip
trays to collect the fat so it doesn't catch fire. The motor is
attached to the pole protruding from the end of the cage. It would
be inflexible if you wanted a larger pig next time but it does
away with the tedious wiring and tying of the carcase. |

A correspondent recently told us of a most ingenious device for rotating
the spit. "A spit roast method I saw used in Bosnia during the war.
A half lamb rack was skewered through (and probably wired up too) over
a charcoal bed, but it was the rotating method that was particularly impressive:
it was a bicycle wheel threaded onto the end of the skewer with plastic
cups taped around the rim where the tyre would have sat. The skewer was
then propelled by a garden hose feeding water to the cups, the speed being
regulated by turning the tap flow up or down.
Crude but effective and the best lamb butty I've ever eaten."
We are often asked what would be the most suitable motor to create your
own spit roast. Here is the opinion of a local engineer. Does anyone have
other opinions?
1. The ideal
engineering solution would be a small geared motor running off
mains voltage. The gearbox is an integral part of the motor and
gives you a very low speed/high torque output from a relatively
small motor. The downside is that I can't think of any domestic
products that would use one of these, so they may not be so easy
to pick up as scrap. Here's
an example .
2. If you want a very cheap 'scrap-yard challenge'
solution, the best I can think of would be to try to find a washing
machine or tumble drier motor. The drums are usually driven by
a speed reduction belt-pulley arrangement. We would probably need
a further speed reduction to get the very low 1 rpm or so required.
These have the advantage of running off mains voltage.
3. If you go for the car solution, you could
probably find a starter motor, which would have the required power,
but would also need gearing down. The downside of car motors is
that they run off 12V DC so you would need a DC power supply. |

Cooking Times
We used to aim for cooking times of 7-8 hours for a 80 pound pig or 8-9
hours for a 100 pound pig and 5 hours for a lamb. Several times we have
taken lambs off earlier than planned because they are more likely to burn
on the outside. The problem then is that they cool off and after cutting
into slices have to be given a second cooking on a barbecue.
In those days before our stainless steel boxes and charcoal, cooking
times were generally longer. Now that we enclose the beasts, times
are significantly shorter. Typically, the lambs cook in 3 hours,
but sometimes 21/2 hours is sufficient depending on how stoked the charcoal
boxes are at the outset. The pork (140lb pig) goes on at 5:00am
and is ready at 11:30 – 61/2 hours. Beef (200lb total) on
at 4am and ready by 12:00 noon – 8 hours but this is to “pink”
medium rare on average with some parts better done and lots still on the
rare side. As it stays over the heat after being carved, it continues
to cook while the mass of meat reduces. This aspect is down to your
judgment.
