How To Pickle Red Onions
Only 10 minutes stands between you and a jar of quick pickled red onions. Of course this doesn’t include the recommended hour or marinating time, but that’s not a hard and fast rule. Here’s how to make pickled onions:
Step 1. Slice the onions as thin and evenly as possible. I recommend using a Mandoline for best results.
Step 2. Stuff as many sliced onions as possible into a large jar. We use these glass mason jars (16 oz).
Step 3. Add the vinegar, sugar, salt and water to a bowl and stir until the sugar and salt are dissolved.
Step 4. Pour the vinegar mixture over the onions and marinate for an hour before digging. Sure – that’s not a requirement but it does maximize the flavor.
What is the Best Vinegar For Pickling?
There are quite a few different vinegars that will work – each has pros and cons. Here are the top varieties:
Distilled White Vinegar
Most commonly used vinegar for pickling vegetables. It’s my preferred go-to vinegar for most vegetables, other than red onions.
Malt Vinegar
Malt vinegar has a very bold flavor and adds a brown tint. It’s best to utilize on produce with a strong flavor that can hold up to it. It’s not my favorite, but it works.
Cider Vinegar
Cider vinegar is a great option. It has a distinct flavor, lends a sweetness to the final product and is probably an ingredient you probably already have. Just make sure to check the acidity level. It MUST be over 5%. An acidity level under 5% won’t properly preserve the product.
Wine Vinegar
Another great option for picking as it has a delicate flavor and lends just a slight color. As with cider vinegar, you must ensure the acidity level is over 5% to use.
