National Julienne Fries Day is observed in the United States every August 12. This day celebrates julienne fries, a type of french fry that is thinner than regular fries, often referred to as shoestring fries. The term “julienne” refers to a culinary knife cut where food is sliced into long thin strips, and when applied to potatoes, it can also be called alumette, meaning “matchstick” in French. The typical measurement for julienne is approximately 1/8 inch by 1/8 inch by 1-2 inches. To celebrate, people often prepare shoestring fries at home, which can be made from both regular and sweet potatoes, and serve them with truffle aioli for added flavor. The aioli can be made by whisking together sour cream or crème fraiche, mayonnaise, white truffle oil, lemon zest, grated garlic, and seasoning.
