<human>:  How can I make a beef curry for 4 people?
<bot>: Start by getting 4 pounds of beef. Cut it into cubes and set aside. Heat some oil in a large pot and add diced onions, garlic, and ginger. Cook until the onions are soft and fragrant. Add the beef cubes and cook until browned. Add two tablespoons of curry powder and stir to coat the beef. Add a can of diced tomatoes, a cup of beef stock and a tablespoon of sugar. Simmer for about 30 minutes, or until beef is fully cooked and the sauce has thickened. Serve with basmati rice and enjoy!
