How do I make a hamburger?
There are many recipes for hamburgers including different buns, patties, sauces, vegetables, and other ingredients. Here is a typical recipe:

Ingredients for 4 burgers:

- 1 pound of ground lean beef.
- 1 large egg
- 1/2 cup of minced onion
- 1-2 cloves of peeled and minced garlic
- 1/4 cup of dried crushed crackers or bread crumbs
- 1 tablespoon of Worcestershire sauce
- 1/2 teaspoon of salt
- 1/4 teaspoon of pepper
- 4 hamburger buns

Optional:

- 4 rinsed and crisped lettuce leaves
- Cored and sliced tomato
- sliced red onion
- mayonnaise
- ketchup
- 4 slices of American cheese

Steps:

1. Mix the ground beef, egg, onion, bread crumbs, Worcestershire sauce, garlic, salt, and pepper in a large bowl until well blended. Make the mixture into 4 patties of about 4 inches wide.
2. Preheat an oiled grill or skillet to medium heat at approximately 350-400 °F (180-200 °C). Grill each side of the patties for 3-4 minutes. Place the cheese slices on top of the patties in the last minute to melt them.
3. Split the buns and lay them cut side down on the grill or skillet. Cook for 30 seconds to 1 minute until lightly toasted.
4. According to your taste, spread mayonnaise and ketchup on bun bottoms. Add the lettuce, sliced onion, burger, and sliced tomato. You can also add extra salt and pepper. Finally, place bun tops.
