I have a jar of white pickled onions (large ones, not the small ones), in white vinegar. We didn't really like them but I really hate throwing good food away. I keep wondering what a beef stew with said pickled onions would be like? Has anyone tried cooking with pickled onions in this way? Would you rinse them first, or just drain them? Better still, have you got a tried and tested recipe? I think I would like to use the slow cooker.
The vinegar in the onions will spoil the taste of anything in a stew.
I don't think there is much you can do with picked onions apart eating them in salad or with cold meat. I hate the things , we have jars of them that were out of date years ago.
Drain the vinegar and rinse the onions in water and dry them out on kitchen paper. Then make some cheese on toast, slice the onions when the cheese is nearly ready and put them on the cheese and back under the grill until the onions have just begun to brown. Top with ketchup or brown sauce and you have a delicious snack. Add salad and you have a great meal.
I do a tuna dish that we first had in Portugal as a starter
it is just a tin of tuna ,drained if it is in brine, mixed with olive oil, chopped coriander, and chopped white silverskin onions, (quantities to your own taste) them eat with fresh bread or savoury biscuits
