Every autumn, we’re given the opportunity to harvest an enormous amount of quinces — usually an entire tree’s worth. Quinces are one of those fruits that, although delicious, can’t be eaten raw like an apple or a pear (even though they’re closely related). They need thorough cooking to become edible, which makes them perfect for cordials, syrups, and preserves. This Instant Pot Quince Butter is the easiest way I’ve found to transform them — quick to prepare, deeply fragrant, and perfectly cooked by the pressure cooker to unlock all that hidden flavour and warmth.
What is Quince Butter?
Despite its name, quince butter contains no actual butter, and is 100% vegan — the term simply describes its rich, spreadable texture.
Like the more well known “apple butter” (known in Dutch as appelstroop and in German as Apfelkraut), it’s made by slowly cooking fruit until its natural sugars caramelise, creating an intense fruit preserve that will keep for months. It is effectively and extremely concentrated juice.
In Europe, fruit butters and syrups have a long history. Monks in the Rhineland and Low Countries began simmering down apples and pears during the Middle Ages to preserve their orchard harvests. In the Netherlands, appelstroop is often spread on bread with cheese or served alongside Sauerbraten, while Belgium favours a sweeter pear-and-apple version called sirop de Liège. Similar syrups exist in Switzerland (vin cuit), showing how widespread this old preservation method once was.
Quince butter follows the same principle — long, slow cooking that transforms firm, astringent quinces into a thick, rose-tinted spread with a honeyed aroma and subtle tartness.
Ingredients Breakdown
Quinces
Quinces have a firm, grainy texture and a floral perfume that deepens into honeyed sweetness once cooked. Their natural pectin helps the butter thicken superbly. There is no need to peel the skins as they will add both and body. Just make sure to scrub them first to remove the fuzzy layer on the skin.
Apple Cider Vinegar
The tang of vinegar cuts through quince’s richness and the acidity will help change the quince colour from beige to that deep rosy pink that quince is known for.
Spices (Cinnamon, Cloves, Allspice, Nutmeg)
These transform the butter from simple fruit purée into a spiced autumn preserve. You can play around with whatever spices you feel like here. I chose these because the give a bit of warmth and amplify that autumn feeling. Cardamom and star anise also work very well with quince. Just be sure to go sparingly with whatever you use. Quince has a delicate flavour and you don’t want to overpower it with too much spice.
Sugar
Unlike apples, quinces aren’t naturally very sweet — they’re tart and tannic when raw. That’s why a touch of added sugar (or honey) makes all the difference, helping balance the acidity and bring out their floral, fruity notes.
Start with a small amount of sugar, and readjust after blending. The cooking process will sweeten the quinces, but how much varies massively from fruit to fruit, so it’s better to be conservative to begin with and then adjust from there.
How to Make Instant Pot Quince Butter
Rub off the fuzzy coating from the skins, then core and chop the fruit into chunks. There’s no need to peel them unless you prefer a lighter colour — the skins help the butter thicken and add depth of flavour.
If you’re using whole spices, lightly crush them with the back of a spoon or a mortar and pestle before adding them to the pot. This helps release their oils and gives the butter a more rounded, aromatic flavour.
Add the chopped quinces to an Instant Pot or pressure cooker. Pour in the apple cider vinegar, half the sugar, and water, then add the crushed spices — cinnamon stick, cloves, allspice, nutmeg — and a pinch of salt. Give it a good stir to make sure the spices are well distributed.
Lock the lid and cook on High Pressure for 40 minutes. Let the pressure release naturally — this helps the fruit stay rich and aromatic. The natural release will take around 15 minutes.
Remove the whole spices, then use a stick blender to purée the quinces directly in the pot until smooth. You can also blend in batches in a regular blender if you prefer.
Stir in more sugar or honey to taste. Keep the Instant Pot set to Sous Vide at 90 degrees and leave uncovered for 2 hours, stirring every 15 minutes or so, until the mixture thickens and turns a deep rose-gold colour.
For faster thickening, use Sauté (Low) for 20-30 minutes, but be careful. Quince burns very fast, so you need to be very vigilant if doing it this way. I recommend the slower, less stressful method of using Sous Vide .
After two hours, the quince butter should be a deep pink colour and thick enough that it will remain on a spoon held upside down. When you’re happy with the consistency, turn off the Instant Pot and let the quince butter cool completely — it firms up as it cools. Transfer to clean jars, seal, and refrigerate.
Storage & Canning
Refrigerator
Once cooled, spoon the quince butter into clean, sterilised jars and seal. It will keep perfectly well in the fridge for around 3–4 weeks.
Freezer
For longer storage, divide the cooled butter into freezer-safe containers or jars, leaving about 1 cm of space at the top for expansion. It will keep for up to 6 months.
Make it Shelf-Stable
If you want to store your quince butter outside the fridge, you’ll need to properly can it. Fill hot, sterilised jars with the quince butter while it’s still hot, leaving 1 cm (½ inch) of headspace. Wipe the rims, seal with new lids, and process in a boiling water bath for 10 minutes (for jars up to 500 ml).
Note on Preservation
Chutneys often keep well when simply poured hot into sterilised jars because their high vinegar and salt content makes them naturally acidic. Quince butter, however, is much lower in acid and has a smoother, moister texture — conditions that aren’t as shelf-stable. For long-term storage outside the fridge, it’s best to process the jars in a boiling water bath for 10 minutes to ensure a proper seal and safe preservation.
Instant Pot Quince Butter
Ingredients
- 1.5 kg quinces — fuzz rubbed off, cored, chopped peel optional
- 50 ml apple cider vinegar
- 80 ml water
- 1 small cinnamon stick
- 3 whole cloves lightly crushed
- 3 whole allspice berries lightly crushed
- 0.5 tsp nutmeg grated
- 1 pinches sea salt
- 75 g sugar start small; adjust after blending
Instructions
- Rub off the fuzzy coating on the skins, then core and chop the fruit into chunks. There’s no need to peel unless you prefer a lighter colour — the skins help the butter thicken and deepen in flavour.
- Lightly crush the cinnamon, cloves, and allspice using the back of a spoon or mortar and pestle to help release their oils.
- Add the chopped quinces, vinegar, water, crushed spices, nutmeg, and salt to an Instant Pot or pressure cooker. Stir to combine.
- Lock the lid and cook on High Pressure for 40 minutes. Allow a Natural Release (about 15 minutes) to let the fruit soften fully and the flavours settle.
- Carefully fish out the cinnamon stick and any whole spice pieces.
- Use a stick blender to purée the quinces directly in the pot until completely smooth.
- Stir in extra sugar to taste. Switch the Instant Pot to Sous Vide at 90 degrees, leave the lid off, and leave for 2 hours, stirring every 15–20 minutes, until the mixture is thick, glossy, and holds its shape on a spoon.
- Spoon into clean jars. Let cool to room temperature — it will firm up further as it cools. Store in the fridge unless you plan on canning the jars.
Notes
- Vanilla Quince Butter: Add half a vanilla pod or 1 tsp vanilla extract after blending for a mellow, dessert-like twist.
- Citrus-Spiced: Add a few strips of orange or lemon peel while cooking to brighten the flavour.
- Ginger Quince Butter: Stir in ½ tsp freshly grated ginger or a few slices of fresh ginger for gentle warmth.
- Herbal Twist: A tiny sprig of rosemary or thyme gives a subtle savoury edge — lovely with cheese.
