Ever wondered what magic your grandma was putting into those jars when you were growing up? I have.
…and never really investigated until now. Living on the opposite side of the world now – where people hang upside down – no written records could be found either. Not that I would have been able to read my grandmother’s old German handwriting.
What helped was this marvellous hande-made stone pot, which Babak imports from Iran. Google came to the rescue when my neighbours plum tree was dumping a ton of fruit on the lawn. Add New Zealand plums, a faint memory of childhood Bliss, a ‘googled’ a.k.a. ‘researched’ German recipe, and a Persian stone pot and voila! There it is: A perfect plum jam/Pflaumenmus that comes very close to Grandma/Oma Lieselotte’s magic!
Just in case you don’t have a Persian stone pot, get one! Haha! Of course, you can probably use your ‘Roemertopf’, still remembering its 1970’s glorious days. A good old (and boring) baking dish with lid will highly likely do the trick too.
You can get these pots in Auckland, NZ, from the Wise Cicada in Newmarket or Farro Fresh.
The original recipe was with brown sugar. I took the freedom to replace it with organic coconut sugar. Have also ramped up the variety of spices. The apricot kernels are there for some bitterness. I remember the highlight of my grandmother’s ‘Pflaumenmus’ always was the whole walnut in each jar. They were delicious when you opened them after they had months to marinate in plum aroma.
If you have fresh (mold free) walnuts, make sure to bake them with the plums to sterilise them. Remember to fish them out temporarily while you puree the plums with your hand mixer! Back in they go afterwards.
Here we go:
Pflaumenmus / German Plum Jam
Prep Time: 3 hours | Cook Time: 2 hours | Servings: 3 liters | Difficulty: Easy
3 kg plums, really ripe
200 g organic golden sugar
300 g organic coconut sugar
2 T cinnamon
5 cloves, ground
10 cardamom seeds, ground
1/4 t vanilla powder
1 star anise, ground
3 apricot kernels, whole (alternatively use 3 whole walnuts)
1 pinch sea salt
Clean the plums, half them and remove the stones.
Toss the plums with the sugars and ground spices.
Put into a stone pot or baking dish and let sit for 2-3 hours to release some of the juice.
To save time you could also boil the plums with sugar and spices in a pot to realease the juice.
If using a stone pot put it into your oven, leave the lid off the pot, but in the oven, so it warms up too. With your oven set to Baking or Fan Baking start with 120°C for 20 minutes. Increase the temperature every 20 minutes by 20°C (total 60 min) until you reach 180°C. Now put the lid on your pot and bake (no fan) for another 60 min at 180°C.
This will allow your stone pot to heat up evenly without running the risk of cracking. The fan in the first hour will allow a good portion of water to evaporate, which makes for a thicker jam.
At the end of the baking time carefully lift out your hot stone pot. Place it on a heat resistant and stable surface. Now puree the plums with a stick blender into a smooth consistency. Remember to fish out the whole walnuts before blending – if you use that variation!
Fill the jam into hot rinsed canning jars. Turn the closed jars onto their lids and let cool down. Having the jars cool upside down will increase the percentage of properly sealed jars drastically – especially when using recycled ones.
Will keep in your pantry until discovered by your family.
Now get yourself a slice of freshly toasted rye sourdough bread or grain-free almond bread with a decent LAYER of butter (wait a bit or your butter will drip!) a spoon… I’m sure you get my drift.
