Nuts & Dried Fruits: How to Buy, Store and Actually Use Them

Nuts and dried fruit are the two categories where most people buy badly without ever realising it. Not because they pick the wrong variety — because nuts go quietly rancid long before they taste obviously off, and dried fruit hides sugar, sulphites and oil behind wholesome packaging. Both problems are easy to avoid once you know what to look at.

This guide covers how to buy, how to store, how to actually use them, and a reference for every major nut and dried fruit.

The nut problem: rancidity

Nuts are high in natural oils, and oils oxidise on contact with air, light and warmth. The result is rancidity — and the reason it catches people out is that it develops gradually. Long before a nut tastes obviously bad, it tastes slightly bitter, slightly flat, a bit like cardboard. Most people blame the recipe.

How to tell: smell them. Fresh nuts smell sweet, buttery and faintly milky. Rancid ones smell sharp, like old cooking oil or paint. Taste one — bitterness at the back of the tongue is the giveaway.

What actually protects you is turnover, not certification. Buy from somewhere that sells a lot, buy quantities you'll genuinely finish, and store them properly. This matters more for nuts than almost anything else you'll buy.

Storage, properly

  • Pantry: fine for a month or two in a sealed container, cool and dark.
  • Fridge: the right default for anything you're keeping longer. Extends life several months.
  • Freezer: best for bulk. Nuts freeze beautifully for up to a year with no texture loss, and you can use them straight from frozen.
  • Highest risk: walnuts, pistachios, brazil nuts and almond meal — the oiliest, and the first to turn. Almond meal especially, because grinding exposes all that surface area at once. Refrigerate it.

Nut by nut

Nut Character Best for
Almonds Firm, sweet, mild Snacking, baking, milk, toasting whole
Cashews Soft, creamy, buttery Curries, stir-fries, blending into sauces
Walnuts Rich, slightly tannic Baking, salads, pesto — goes rancid fastest
Brazil nuts Dense, creamy, distinctive Snacking, chopping into granola
Pistachios Sweet, faintly resinous Snacking, Middle Eastern sweets, garnish
Almond meal Ground, moist, nutty Gluten-free baking, frangipane, crumbles

How to toast nuts (properly)

Toasting is the biggest upgrade available and takes eight minutes. It drives off moisture, deepens the flavour and dramatically improves texture.

  1. Oven at 160°C — low and slow beats hot and fast, which browns the outside before the middle develops.
  2. Single layer on a tray. 8–12 minutes depending on size.
  3. Shake the tray halfway and start checking at 8 minutes. Go by smell.
  4. Tip onto a cold plate immediately — they keep cooking on a hot tray.
  5. Cool completely before chopping or storing. Warm nuts sweat and go soft.

Toast only what you'll use within a week or two — toasting speeds up oxidation, so toasted nuts don't keep as long as raw.

The dried fruit problem: what's on the label

Three things to check, none of which is the word "natural":

  • Sulphites (E220 / sulphur dioxide). Used to keep dried apricots and mango bright orange. Naturally dried fruit turns brown — that's ripening sugar caramelising, not a defect, and it usually tastes deeper. Some people are sensitive to sulphites, so it's worth knowing which you're buying. Our organic Turkish apricots are the naturally dried style.
  • Added sugar. Standard in cranberries, which are too tart to eat otherwise. The question is what they're sweetened with — ours use apple juice rather than refined sugar. Also common in mango and banana chips.
  • Oil coating. Raisins, sultanas and currants are often lightly coated to stop them clumping. Harmless, but it's there.

Dried fruit keeps far better than nuts — low oil, low moisture. Airtight at room temperature is fine for months; refrigerate in a humid Auckland summer if it's softening or sticking.

Dried fruit by type

Fruit Character Best for
Dates Intensely sweet, caramel, soft Bliss balls, natural sweetening, tagines
Raisins & sultanas Sweet, chewy, familiar Baking, muesli, pilaf, chutneys
Figs Honeyed, seedy, jammy Cheese boards, baking, stuffing
Apricots Tart-sweet, bright Tagines, stuffing, snacking, granola
Cranberries Tart, chewy Salads, baking, muesli
Currants Small, tangy, concentrated Fruit cake, scones, Middle Eastern rice
Mango Tropical, chewy, tangy Snacking, trail mix
Banana chips Crisp, sweet Trail mix, topping granola

Plumping dried fruit

Hard, dry fruit isn't finished — it just needs rehydrating. Cover with hot water, tea, juice or a spirit and leave 15–30 minutes. Transforms fruit cake, scones and tagines, and stops dried fruit stealing moisture from your batter as it bakes.

Dates as a sweetener

Worth its own section because it's the most useful trick in this category. Blended dates replace refined sugar in a lot of baking and no-bake recipes, bringing fibre and a caramel depth sugar doesn't have.

Date paste: soak 200 g pitted dates in hot water for 20 minutes, drain (keep the liquid), then blend with 3–4 tbsp of the soaking water until smooth. Keeps a fortnight in the fridge.

Rough substitution: use about ¾ cup date paste per 1 cup sugar, and reduce the other liquid slightly. It works best in dense bakes — brownies, muffins, slices — rather than light sponges, where sugar's structural role matters.

Spices that make them better

Frequently asked questions

How do I know if nuts have gone rancid?

Smell first — sharp, oily or paint-like rather than sweet and buttery. Then taste one; bitterness at the back of the tongue is the tell. Rancid nuts won't make you ill but they'll spoil whatever you put them in.

Should I keep nuts in the fridge?

For anything beyond a month or two, yes. The freezer is better still for bulk — up to a year with no loss of texture, and you can use them straight from frozen.

Why are some dried apricots orange and others brown?

Orange ones have been treated with sulphur dioxide to preserve the colour. Brown ones are naturally dried. The brown ones typically taste richer and more caramelised.

Is dried fruit just sugar?

Drying removes water, so the natural sugars concentrate — that's why it's sweet and why portions are small. Whether there's added sugar on top is a separate question, and it's on the label.

How long does dried fruit last?

Six to twelve months in an airtight container, cool and dark. Much more forgiving than nuts. If it hardens, plump it in hot water rather than throwing it out.

Can I substitute one dried fruit for another in baking?

Mostly yes, by weight. Raisins, sultanas and currants are near-interchangeable. Chopped dates, figs and apricots work too, though dates are much sweeter, so ease back on the sugar.

Are organic nuts worth it?

Less critical than for superfood powders. For nuts, freshness and turnover matter more than certification — a fresh conventional nut beats a rancid organic one every time. Our organic buying guide ranks where the premium is genuinely worth paying.
