The most important factor in making the best burger is the quality of the beef. It should be high-quality ground beef, preferably freshly ground on-site. Other key ingredients to consider are a good bun or bun alternative, cheese and toppings such as lettuce, onion, pickles, and tomatoes. Finally, don't forget about condiments like mayonnaise, mustard, ketchup, and relish for that extra flavor!
