Zwetschgen Season: Cheap Swiss Plum Recipes

In late August, Swiss Zwetschgen hit their annual low of about CHF 2 per kilo on Aktion. The three recipes that clear a glut fastest are a Zwetschgenwähe (plum tart) at roughly CHF 0.38 a slice, a spiced compote for breakfast, and a chutney that keeps for months. All three cost a fraction of the bakery or deli equivalent.

Work a CHF 4 two-kilo crate into a plum tart, six portions of compote and a batch of chutney, and you replace CHF 25–30 of supermarket pastries, spreads and condiments — while throwing nothing away.

When are Zwetschgen cheapest in Switzerland?

Zwetschgen — the small, oval Swiss prune plums with firm flesh that holds its shape when cooked — are a late-summer fruit. Domestic supply builds from mid-August, peaks around the turn of the month into early September, and that surge is what pushes the price down. On Aktion you will see roughly CHF 1.90–2.50 per kilo at Coop, Migros, Lidl and Aldi, against CHF 4–5 for the first imported plums in July or for out-of-season fruit later in the year.

They arrive as the wider stone-fruit season winds down, so if apricots and nectarines are still on your list, our stone-fruit buying guide has the full price calendar. The rule for Zwetschgen is short and simple: buy a crate at the peak, because the window rarely lasts more than a few weeks and prices climb again by late September.

Zwetschgenwähe: the CHF 0.38 slice

The Wähe is the Swiss take on a plum tart: a thin dough, a scatter of ground hazelnuts or semolina to soak up the juice, halved plums packed tight cut-side up, and a light dusting of sugar and cinnamon. One kilo of Zwetschgen fills a standard round tin or a small baking sheet and yields about twelve slices.

• 1 kg Zwetschgen — CHF 2.00 on Aktion
• Dough (flour, butter, a little milk and salt) — about CHF 1.50, or a ready-rolled Kuchenteig for around CHF 2.50
• Sugar, cinnamon and a handful of ground nuts — about CHF 1.00

That is roughly CHF 4.50 for the whole tart, or CHF 0.38 a slice. Bake at 200°C for 35–40 minutes until the edges catch and caramelise. It keeps three days under a cloth and freezes well — slice it before freezing so you can pull out one piece at a time for a Znüni or Zvieri.

A compote for breakfast, dessert and the freezer

Compote is the lowest-effort way to rescue soft or slightly bruised fruit that will not last on the shelf. Stone and quarter 1 kg of Zwetschgen, add three or four tablespoons of sugar, a cinnamon stick and a splash of water, then simmer for about fifteen minutes until the fruit slumps. That is six generous portions for roughly CHF 2.50 — about CHF 0.42 each — spooned over yoghurt, porridge or Bircher, or served warm with a scoop of vanilla.

The hob does all the work, so it will not heat the flat the way an oven does. If you are cooking through a late-August heatwave, the same no-heat logic runs through our no-oven summer desserts. Compote keeps a week in the fridge and freezes for six months in portion tubs.

Zwetschgen chutney: the jar that lifts a raclette

Chutney is where a glut turns into a store-cupboard asset. Cook 1 kg of stoned Zwetschgen down with a chopped onion, 150 ml vinegar, 150 g sugar and whatever warm spices you have in — cinnamon, star anise, a pinch of chilli, a little grated ginger — for about forty-five minutes until thick and glossy. It fills roughly four small jars.

Total cost lands near CHF 4.00, or about CHF 0.10 per tablespoon, against CHF 4–6 for a bought jar half the size. Sealed in sterilised jars it keeps six to twelve months, and it turns a plate of Swiss cheese, a raclette or a spread of cold cuts into something that tastes deliberate. It also makes a respectable Christmas gift built from fruit you bought in August.

What does each recipe cost per portion?

Here is the whole plan on one line each — how much fruit you need, what it costs, and how long it lasts once made:

How do you preserve a plum glut?

Preserving is the difference between a bargain and a bin. Swiss households throw away a striking amount of food: according to the Federal Office for the Environment (BAFU), households are responsible for about 38% of Swiss food waste — roughly 119 kg per person every year — and seasonal fruit gluts are a classic culprit. A crate bought cheap and left to turn is a false economy.

Freezing is the fastest fix: halve and stone the plums, freeze them flat on a tray so they stay loose, then bag them for up to a year. Canning suits compote and chutney; the fridge shelf handles the week ahead. The same freeze-can-pickle routine works for the whole summer harvest, and we lay it out step by step in how to preserve summer produce.

Turn a crate into a season: the step-by-step

A single CHF 4 two-kilo crate, worked through in one evening, covers dessert now and flavour for months:

1. Buy at the peak. Wait for the Aktion at CHF 2/kg or under, and pick up two or three kilos rather than a single punnet.
2. Sort on arrival. Separate the soft and bruised from the firm — the soft go to compote today, the firm keep for chutney and the freezer.
3. Bake first. Turn the ripest kilo into a Wähe while the oven is on; slice and freeze whatever you will not eat within three days.
4. Simmer a compote from the softest fruit, then portion it into tubs for the week and the freezer.
5. Cook the chutney from the firm fruit and seal it in sterilised jars for the winter.
6. Freeze the rest halved and stoned, in labelled 500 g bags.

How Eini turns a plum glut into a plan

The catch with seasonal cooking is timing: the saving only exists during the short window when Zwetschgen sit at CHF 2. That is exactly what Eini's algorithm watches. It tracks current fruit and vegetable promotions across Coop, Migros, Lidl, Aldi, Denner and Aligro, so the moment plums reach their seasonal floor, the deal turns up in your list — no flyer-reading required.

From there it fits the fruit into your meal plan and builds the shopping list around it, so a plum Aktion becomes a Wähe on Saturday and a row of chutney jars for the cupboard, rather than a crate forgotten on the counter. Groceries and meal planning are what Eini does today; download it and let the algorithm keep an eye on the season for you.
