Membrillo is a thickened and sliceable fruit paste, to accompany cheese platters, prepared in autumn, almost always with quince, and sometimes with apples & pears and never, to my knowledge with strawberry tree berries, which grow in our garden, so I gave it a try !

The scientific name of the strawberry tree is ‘arbutus unedo’ and sometimes called ‘madrone’. The sweet and tangy arbutus berries with tiny seeds throughout the flesh (similar to strawberry seeds) are used to make jams, marmalades and strong alcoholic beverages, especially in Portugal and Albania. It mostly grows around the Mediterranean basin but can thrive in colder climates like in our Paris garden and in southern and western Ireland, known as the ‘cane apple'.

We have 3 tall strawberry trees, 2-3 meters tall in our shared garden in Paris, and apart from the birds, no one picks nor eats them and they end up on the ground. The tree manages to simultaneously produce blossoms, the next berries to ripen which are still yellow and orange and this season’s bright red ripe berries.

I decided to pick about 1 kg of fruits and used half to try to make some candied berries in syrup, but they easily fell apart while simmering. They seemed to turn into a jam quite quickly, since they’re rich in pectin, so I decided to keep simmering them until they thickened some more and transferred the mixture to a large square Tupperware and left it out to cool and then refrigerated it. 

Two days later, I decided to have some bread with butter and strawberry tree berry jam. The mixture was so thick that it had to be scraped out, like the cold butter and when I unmolded it, it retained the cubic shape of the plastic container. This is when I thought I could try to make a 2nd batch and make little rectangles of strawberry tree berry “membrillo”, because I liked the taste as well as the grainy texture, which could be more interesting when accompanying a cheese platter.

I kept it simple and used citrus juices, the empty rinds, sugar, a pinch of salt and fresh bay leaves and rosemary, to macerate everything overnight and I used those extracted juices to simmer the fruits (without adding any water).

The end result is a deliciously sweet, slightly tangy, dense and textured (because of the tiny seeds) “membrillo” paste that was a perfect to accompany our cheese, charcuterie and little “pico” breads (see recipe here) platter, with so much leftover membrillo cubes, that I froze them for another occasion.

Experimentation makes food preparation more satisfying … :)

strawberry tree berries «membrillo» paste

01.11.2025

650 grams or 2 cups

ingredients

  • 500 grams (4 cups) strawberry tree berries
  • 500 grams (2 ½ cups) extra fine sugar
  • 120 ml (4 tbsp + 3 tbsp + 1 tbsp) citrus juices (orange, lemon & lime) 
  • 120 grams (½ cup) sliced citrus rinds (after pressing or juicing them)
  • optional : 2 grams (1 stem) fresh rosemary
  • optional : 1 gram (2 whole) fresh bay leaves
  • 1,25 grams (¼ tsp) fine sea salt

instructions

  • wash & strain fruits and transfer to a large flat bowl, toss with the citrus juices and salt and add the sugar and citrus peels, cover loosely and let sit at room temperature for 18-24 hours (to release the juices) and stir occasionally
  • *note : after 24 hours, you will end up with approximately 400 grams berries and 650 grams juices and sugar mixture … 
  • strain the fruits and set them aside and recuperate the juices and peels and transfer to a large saucepan, add the rosemary and/or bay leaves and bring to a boil, then lower heat to low and simmer very gently for 5-10 minutes, then remove the peels and herbs
  • add the shriveled berries to the pre-boiled juice and sugar mixture, bring to a boil, then reduce the heat to low and simmer very gently for 10-15 minutes, until most of the berries break down, then use a fork or potato masher to crush the remaining partly whole fruits and keep simmering for another 10-15 minutes until very thick, stirring often with a wooden spoon
  • *note : if you would like to have some jam, you can cook the fruits only for the first 15 minutes and then store the hot jam in hot sterilized jars, otherwise continue simmering as indicated for the thicker paste …
  • when the mixture is thicker, like a paste or glue, transfer the warm mixture to a plastic storage tub or smaller silicone molds, smooth out and let sit and harden at room temperature for at least 1-2 days
  • unmold the individual larger block or many smaller blocks (it may be easier to unmold from silicone molds if you freeze them solid before) and lay them out on baking paper and let the paste blocks dry out, on the kitchen counter, for another day or two until firmer, then wrap in baking paper and plastic film and refrigerate (or freeze) 
  • serve the membrillo strawberry tree berry paste at room temperature, in slices, with cheeses and breads.
