Take a bowl. Put mayonnaise, ketchup, lemon juice, Worcestershire sauce, and mustard powder in it. Mix everything well.
If you want heat from your sauce, just add a few drops of hot sauce into the mixture.
Whisk everything in the bowl until the sauce becomes creamy and smooth.
Taste the sauce to see if everything is in the right proportion. If needed, add some more lemon juice or mayo.
Refrigerate the sauce for at least 30 minutes before you serve.
Now you can enjoy your sauce. Store the leftover sauce in the refrigerator in an airtight container.
