Home grown firewood is not in plentiful supply here in Shetland. However, a washed up beach log or even some scrap lumber, plus a small quantity of kindling and a Loki's Candle fire starter can provide enough flame to cook a meal over using the Nordic Fire Log technique (aka Swedish Fire Torch or Canadian Candle), as demonstrated here by physics teacher Chris McGinley.
Chris, originally from the mainland of Scotland, has called Shetland home since 1996 when he accepted a teaching position on the island. An outdoor enthusiast, Chris enjoys camping and bushcrafting, and, this past weekend he kindly agreed to teach me how to cook over a Nordic Fire Log, a technique taught to him by his brother who lives in Sweden.
To prepare your log, carefully use an axe (or chainsaw) to divide a one foot long log with a flat top and bottom into four quarters. Find a sheltered, level location for your fire, and arrange the four quarters slightly apart.
