Garden childhood memory

I still remember the scent of dill in my Grandmother’s mud room. My sister and I would play for hours in the now-torn-down farm house on Vilas Road in Medford, Oregon. We’d spend hours at Grandma’s house, my mom helping Grandma with harvesting and canning from the garden. As a little girl, I really didn’t have a clue about the hard work that went into farming and gardening. But I do remember the huge bouquets of gladiolas that lined the front porch, and on the old farm table, quart jars filled with dill pickles, peaches, pears, green beans and cherries.

Pint jars of every kind of jam imaginable to man, relishes, tomatoes, and creative sauces. You name it, my Grandma Dubs canned it, or pickled it.

I was never crazy about onions, but like I said, mom taught me an easy way to make them tasty and perfect for different dishes. She also marinated cucumbers this way.

And you can serve the onions this way, in salads, with already cooked meats, or pile them on a sandwich–my all-time favorite!

I recently made my husband a sandwich.

These onions! These onions! Which meant, they are really good!!

Print Recipe Pin Recipe


  • 1 medium to large red onion, ends removed, peeled and halved
  • 2 c boiling water
  • ½ c white vinegar
  • ½ c sherry vinegar
  • ¼ c white sugar
  • 6 peppercorns
  • ¾ tsp kosher salt plus more to taste


  • Using a sharp knife or a mandolin, slice your onion halves in a parallel direction to produce long, 1/4-1/2’’ strips.
  • Bring water to a boil. Place the onions in a colander and pour 1 cup of boiling water over them. This tones down the strong onion flavor and par cooks them.
  • Transfer the remaining water to a small saucepan, along with the vinegars, sugar, and salt. Bring to a boil, then simmer until sugar dissolves—1 minute. Taste and adjust seasonings if needed, then remove from heat.
  • Place onions and peppercorns in a jar and pour warm vinegar over all. Allow to sit at least 45 minutes before serving.
  • Allow onions to come to room temperature before storing in the refrigerator.
