The size of a bundle of asparagus can vary depending on where you purchase it and how it's packaged. Asparagus is typically sold in bunches or bundles, and the quantity in each bundle can depend on factors such as the thickness of the spears and regional packaging standards. On average, a standard bundle of asparagus may contain around 1 pound (approximately 454 grams) of asparagus. However, this can vary, and you might find bundles that are smaller or larger. For these prosciutto wrapped asparagus bundles, you need about 3-4 spears of asparagus per bundle.
