I recommend using salted pretzel twists or sticks for making a pretzel salad crust. These types of pretzels provide the ideal combination of crunch and saltiness that complements the sweet and creamy layers of the dessert. Make sure to crush them finely but not into a powder; you want small pieces that will form a sturdy yet slightly crumbly crust when mixed with melted butter and a bit of sugar. This balance ensures the crust holds together well and offers the perfect texture contrast in your strawberry pretzel salad.
