I pickle cucumbers in brine using about 45 grams of salt per litre of water, stored in a mason jar at room temperature for about a week.
I season them with fresh dill, smashed garlic, a whole chilli pepper, mustard seeds, bay leaf and whole black pepper.
As far as I can tell the cucumbers pickle successfully, but have a metallic aftertaste.
What might be causing the aftertaste and how can I solve it?
