Notes
Shallots have a unique, mild flavor that sets them apart from other onions. But if you're not able to find them, you can use red onions for this recipe.
Apple cider vinegar adds a sweet and tangy flavor to pickled shallots. But, you can use lots of different types of vinegar or whatever you have on hand. White vinegar, white wine vinegar, red wine vinegar, sherry vinegar, etc. will all work.
Mustard seeds and peppercorns add a little extra flavor and texture element to the pickled shallots. But, you can omit them if you'd like.
Pouring the hot pickling liquid over the raw shallots lightly cooks them while also keeping them crunchy. So, there's no need to simmer the shallots in the vinegar.
