What is Walnut Oil?
Why call it “walnut oil” when walnuts aren’t even true nuts? (Surprise! They’re seeds.) Maybe it’s because “juglans regia oil” doesn’t quite roll off the tongue. Or perhaps it’s rooted in folklore: legend says walnut trees were sacred to Jupiter, symbolizing wisdom and abundance. Coincidence that this oil boosts brainpower? We think not.
Jokes aside, walnut oil is cold-pressed from walnuts, capturing their earthy essence in liquid form. It’s the culinary equivalent of a warm hug—rich, comforting, and slightly indulgent. As the old saying goes, “The way to a man’s heart is through his stomach,” and a drizzle of walnut oil over grilled salmon or fresh bread might just do the trick. Curious? Grab a bottle and let’s get cooking!
Why You’ll Love Walnut Oil
