Fermented Nasturiums Seeds and Pesto, mad things to ferment

Nasturium pickle

Nasturiums are gorgeous looking yokes that either love your garden or can’t be arsed growing in it. If it’s the former then you’re in for a treat every year as they self seed at the end of the growing season and come back with a bang the following year, like Freddie Mercury at Live Aid, sadly without the muscle top.

Nasturium flowers are edible and are bought by many chefs to put on dinner plates in fine dining restaurants across the world, sometimes it can cost as much €5 for one carefully packaged bloom. So next time you see these beautiful flowers, from yellow to orange and a vampy, blood red, pick a few and toss them on your salad or your desert plate. You’ll suddenly be eating a very valuable meal. Nasturium seeds have a hidden use, other than being the seeds for the next years flowers, they can be pickled or fermented to make what’s known as poor mans capers. The seed pods are very peppery, just like the flowers and need some time in brine or vinegar to reduce their fireiness and make them more digestible. So the next time you see those unusual looking, plump seed heads like little brains popping off your own flowers, gather them up. They will willingly fall from the plant with a little nudge when they are ripe for the picking. Then you can make some delicious and interesting preserves from more of natures free food. Don’t wait around however, now is the time to get these nasturium seeds before they fall to the ground or dry up. Nasturium leaves are bursting with peppery flavours too and make a great addition to salads as well as being very pretty to look at. You can easily make a zingy nasturium pesto or oil for enjoying with pasta or on a fish dish or salad. Blackfly love these plants so be sure you’re not making your delicacies with a bunch of aphids!

 

Fermented Nasturium Seeds

For one pint you will need a jar that fits this volume, a bit less than one litre, clean and sterilise it by putting it in the oven at 160C for ten minutes or putting it through a dishwasher cycle without a tablet. I made this with and without the garlic, the alium really takes over the flavour but if garlic is your thing then go nuts and pop in plenty.

Ingredients

Collect as many seeds as you can, this recipe will work for about 1 1/2 cups of seeds but you can adjust it accordingly.

Sea Salt

Garlic – optional

Method

Collect your seeds

Dissolve 10g salt in 250ml water to make your brine for fermenting

  1. Rinse the seed pods and peel the garlic cloves, pack the cloves into the jar and top them with the seeds
  2. Pour over the salty brine until it just covers the seeds
  3. Weigh down the seeds with a weight that fits inside the jar, I usually use a smaller jar. It’s important to keep the seeds under the brine or they will go mouldy.
  4. Pop a lid on the jar and put it on a plate to collect and liquid that overflaows. Place this somewhere with an ideal temperature of 18-20 C, however I find that ferments work, no matter really where you put them.
  5. Let any gasses that might build up, out of the jar and after 5-7 days the ‘capers’ will be ready. Keep them in the fridge where they will stay fresh and crunchy for months.
