Recently I was considering what kinds of nut trees I could grow at home. I was disappointed to find out I ought to scratch Macadamia nut trees off the list since they are frost tender, so not really suited to our place. But then, how happy was I to discover, that there are some well-established orchards not too far away near the coast of Thames.
Mark and I are keen to source local, and we were lucky enough to get a tour around ‘Top Notch’ orchard to see how their Macadamias are grown and processed. What I loved about this place was that every part of the nut is used: from the nut itself – in its pure form or with added flavours, processing the nut to make high quality oil, meal and nut butters, to using the husks as mulch.
Macadamia nuts are wee balls of energy (720 – 740 kcal/100g) which makes them one of the highest nuts for calorific value. So a good option to take hiking. Like most nuts, macadamia nuts are high in fat – about 76% fat. But the fat in macadamias is the good kind (such as oleic acid and palmitoleic acid) that help lower heart disease and stroke risk. Macadamia nuts have a small amount of protein (~ 8%), but contain around 7% fibre of which some is soluble and some not so macadamias are a good source of roughage and can help promote feelings of satiety. The nuts are rich in many important B-complex vitamins that are vital for metabolic functions. 100 g of nuts will provide 100% of your daily thiamine requirements, 15% of niacin, 21% of B-6, and 12% of riboflavin requirements. They are an excellent source of minerals such as calcium, iron, manganese, magnesium and zinc too. That 100 g of nuts will also provide 3.6 µg of selenium – which is a cardio-protective trace element, again, keeping that heart healthy.
Macadamia nut interesting stuff:
Macadamia trees are native to Australia, and are known by several other names in Australian Aboriginal languages such as bauple and boombera. Allegedly … the botanical name Macadamia was given to them by a botanist (Baron Ferdinand von Mueller) who named the tree after his friend, Dr. MacAdam. Sadly (ironically), Dr MacAdam died on board a ship that was en route to visit his friend Ferdinand and to taste the very nut named after himself….

PS: we ended up planting an almond tree, so I can write about harvesting that in, say … 15 years…
