No need to do all the overnight soaking business when using a pressure cooker. Oh, can’t tell you when it comes to dishes like this - I so cannot do without my pressure cooker- it makes my life 1 million times easier reducing the cooking time to ⅓. Seriously.
Cook the beans according to the package instructions. Canned beans can also be used. I cook them in pressure cooker for at a 15 min setting. No whistle.
When finished with cooking the beans carefully release the pressure or allow 15-20 min for pressure to go down so you can remove the lid.
Meanwhile, peel, wash and chop the onions and the carrot, wash and chop the leek, pepper and the parsnip.
Add all the vegetables nicely chopped to the cooked beans. Add some vegetable stock or water if there isn’t sufficient liquid. You should have approximately 1 litre of liquid.
Put the bay leaves and the thyme in, the tomato paste and the chopped tomato can, salt and pepper.
Place the lid back on and cook for a further 10min under pressure.
Release the pressure * or allow it to rest until the lid can be safely removed. Remove the lead and set back on cooking for another 15 minutes. Add the turmeric and cook uncovered so that the soup juice reduces slightly. This also helps with the soup getting a nice colour.
In the last five minutes of cooking add the washed and slightly chopped nettles along with the fresh herbs such as lovage, parsley or even some fresh basil what ever you may fancy, like or have handy. Any herb will be nice. Delicious.
