Key species include Chinese hawthorn (Crataegus pinnatifida), which is widely used in Eastern Asia for snacks such as tanghulu and haw flakes, and tejocote (Crataegus mexicana, commonly used in Mexican cuisine, particularly in ponche (a traditional fruit punch) and candies.
Other notable species with culinary relevance include common hawthorn (Crataegus monogyna) and midland hawthorn (Crataegus laevigata), both native to Europe; their berries (haws) are used in jellies, preserves, and beverages.
