I keep coming back to the fact that cacao powder and macadamia pieces each have a one-item ingredient list, which hardly ever happens with anything sold as a snack, and yet people still file them under treats as though that settles it. It doesn't, really, because what makes a meal balanced or not is usually whatever else is sitting on the plate, and a few nuts over plain yoghurt is a very different thing from the same nuts buried in sweetened granola with something sticky drizzled on top. So what follows is a fairly loose run through how the two get used in an ordinary kitchen, with the usual questions answered more or less as they come up.
People use the two words as if they mean the same thing, and labels don't help, but cacao is generally the cold-pressed version, where the fat is squeezed out and the dry part gets ground into powder, while cocoa tends to be roasted at a higher heat and quite often alkalised as well, which is where the redder colour and the softer, flatter taste come from. Whether that extra heat takes much goodness out is something I've seen argued both ways, and the research looks thin enough that I wouldn't lean on it in either direction, so choosing whichever one you actually like the taste of seems fair enough.
Natural cacao powder tends to surprise anyone expecting hot chocolate, because it's sharp and a bit sour, closer to cherry skins than milk chocolate, and it carries some magnesium and iron along with flavanols and a stimulant called theobromine, which is mild but can still keep a sensitive person awake if a heaped spoonful goes into a late-night drink. When you're looking through natural cacao powder online, the ingredient line tells you most of what you need, since it ought to say cacao and nothing else, and if sugar has been added then it's really drinking chocolate with a nicer label on the front.
In baking it mostly swaps in for cocoa at about the same amount, although Cacao powder for baking does come out darker and a touch more bitter than people expect, so taking a spoonful or two of sugar out of a brownie recipe and seeing how the first tray goes is probably safer than following the original amount to the letter. It also drinks up moisture, which means that if the batter looks stodgy once the powder is in, a splash of milk usually loosens it where extra oil would only leave the cake greasy, and sifting it with the flour matters more than it sounds, because dry lumps survive the whole bake and then show up as one bitter pocket in a single muffin.
Organic cacao powder for baking suits the bakes where chocolate has to carry everything, so flourless cake or ganache or a dense slice, mostly because there's no filler in the tub watering it down, and most of those cope fine at somewhere between 160 and 180°C. The tub keeps well too as long as the lid stays tight and it isn't parked beside the kettle, since steam is usually what makes it clump.
For a banana loaf, three ripe bananas and two cups of flour, with three tablespoons of cacao in place of the same amount of flour, is a reasonable starting point, and maybe half a cup of macadamia pieces folded through at the end. Bananas vary so much that I'd go by how the batter drops off the spoon rather than trust the numbers, thick and slow being about right, with a bit of milk or flour fixing anything that's off either way.
Smoothies are where cacao gets overdone most often. Cacao powder for smoothies blends in with banana and oats and whatever milk happens to be open, and a teaspoon is often plenty, two if you like it strong, but go much past that and the whole thing turns gritty and bitter, which is usually how a tub ends up forgotten at the back of the cupboard for a year. If you're hunting for cacao powder for smoothies Australia wide in a smaller size, a 100g tub lasts a surprisingly long time at that rate, and a ripe banana or a couple of soaked dates normally gives enough sweetness without any sugar, with a pinch of cinnamon helping more than you'd think and a little honey being fine so long as it doesn't take over.
Macadamias are Australian natives, mostly monounsaturated fat of the olive oil and avocado sort, low in carbs, with a bit of fibre and some thiamine and manganese, which sounds great and mostly is, apart from the fact that they pack a lot of energy into a small size, a 30g handful being a bit over 200 calories, give or take, and three handfuls vanishing in under a minute if the bag is open next to the telly. Tipping a portion into a bowl and putting the bag away is dull advice, though it does seem to work.
They keep you full as well, and a small scatter over porridge seems to hold off hunger for longer than raisins would, which along with that buttery richness is mostly what people mean when they search macadamia nuts for cooking Australia, because a few tablespoons will cover a whole tray of baking and a bag goes further than it looks. Raw pieces are milder and a little soft, while roasted ones are crunchier with a deeper flavour, and dry-roasted works out lighter than oil-roasted if calories matter to you, whereas salted ones really belong on a snack plate and not so much in a brownie.
Whole nuts look lovely, but they cost more and nobody sees them once they're stirred into a batter, which is why Macadamia pieces for desserts make more sense for cookies and banana bread and crumble toppings, since they arrive already broken up and there's no chopping, and no half a nut turning up under the fridge three weeks later. A handful through brownie batter gives crunch against the soft middle, and toasting them in a dry pan for a few minutes is optional but nice, although macadamias go from golden to bitter quicker than almonds do, so wandering off mid-toast tends to end badly.
They aren't only for sweet food either. Macadamia nut toppings over roast pumpkin or a green salad bring the creamy richness you'd usually reach for cheese to get, and at breakfast, macadamia toppings for breakfast bowls are hard to beat, whether that's a few pieces over yoghurt and berries or pushed into overnight oats where they stay crunchy for ages, which is more than granola ever manages. A teaspoon of cacao through hot porridge with the nuts on top ends up tasting like dessert for about half a minute's work.
For anyone who bakes a fair bit, those small supermarket bags get expensive quickly, so macadamia pieces online are worth a look. When you buy macadamia pieces online Australia wide, it's worth checking whether they're raw or roasted and whether any salt or oil has been added, and then having a sniff once the parcel turns up, because fresh ones smell sweet and a bit creamy while anything sharp, like old paint, means the oil has gone rancid and they're better in the bin.
Bigger households and market-stall bakers usually do better on price with bulk macadamia pieces, although for bulk macadamia pieces Australia buyers I'd say storage matters more than the price tag, since the oil that makes them taste so good is the same oil that turns on a sunny shelf, and an airtight tub somewhere cool and dark, or the fridge once summer hits, saves a lot of money being thrown away.
If you fancy something properly Australian, Wattleseed Ground is roasted and ground acacia seed with a flavour that's hard to pin down, something like coffee and hazelnut and a bit of chocolate all muddled together, and a small spoon through cacao batter seems to deepen the chocolate while also going well beside macadamia cream or plain vanilla ice cream. Half a teaspoon is probably enough the first time, since it's stronger than it looks.
Nobody really needs a meal plan for this, and I'd be a bit wary of anyone who says they do, because for most people it ends up looking like cacao in a smoothie a couple of mornings, macadamia pieces on yoghurt or oats on others, and something baked at the weekend that uses both. If you bake brownies or banana bread on Sunday, freezing half straight away stops the lot disappearing by Tuesday, which is usually the point where "balanced" slips, and the ingredients are fine while the volume of cake around them is the actual problem.
Mistakes tend to be predictable as well, like too much cacao and then blaming the recipe, or nuts toasted at too high a heat, or both tubs stored in a warm cupboard next to the stove, and moving them somewhere cool fixes more than any recipe tweak will.
There's no single number that suits everyone, but for most healthy adults one 30g handful of macadamias and one or two teaspoons of cacao a day is a fair place to start, and the rest of the plate counts for a lot more than either, with vegetables and legumes and wholegrains still doing most of the heavy lifting.
Kids are the exception, since theobromine hits smaller bodies harder, so cacao amounts for them should be kept low, and anyone with a medical condition or regular medication or a nut allergy should check with a doctor or dietitian first, because macadamias are tree nuts and a tree nut allergy is nothing to take lightly.
People often ask whether cacao powder is healthy, and unsweetened it is a source of flavanols and minerals, but once it's in a cake with butter and a cup of sugar it's the cake you're judging, not the powder. Macadamias every day are fine for plenty of people in small handfuls, with unsalted being the better pick. And whether they need roasting first depends on where they're going, since raw is fine inside batters while the ones on top are worth toasting, because that's where anyone actually tastes them.
Wasteless Pantry Bassendean has the organic cacao powder and the macadamia pieces on the product pages linked above. A small tub of each is a sensible way to start, and a cacao and macadamia banana bread is an easy first bake, with the sugar and the toasting adjusted next time round. Balanced eating mostly comes down to habits you can keep up, and these two make a few of them a lot nicer.
