Garlic Butter Sauce
Garlic butter becomes pasta sauce only when fat and water are persuaded to share the pan. Melted butter poured over noodles is pleasant, but it is still melted butter poured over noodles.

Glossy and coating, with no clear butter puddle.
Sweet garlic, clean butter and measured lemon.
What the record supports.
Butter-and-garlic sauces are modern and widely used across South African home cooking, especially with prawns, chicken and steak.
This page teaches a local practical sauce, not an ancient Italian classic.
Every ingredient has a job.
Butter
It carries garlic and forms the fat phase of the emulsion.
Garlic
Gentle heat makes it sweet and aromatic rather than bitter.
Pasta water and lemon
Water emulsifies; lemon cuts richness.
Build it in order.
Salted butter is common locally. Reduce pasta-water salt and taste before adding more.

Pasta that helps.

Substitutions
Olive oil creates a lighter garlic emulsion.
Parsley or chives can replace one another.
Common mistakes
Browning chopped garlic
Adding all pasta water at once
Boiling after the final butter
Storage and freezing
Best fresh; refrigerate leftovers for 2 days.
Freeze the flavoured butter base, not finished emulsified pasta.
Warm gently with water and whisk; high heat will split it.
Add chilli for heat.
Roasted garlic makes a sweeter, softer sauce.
Put the technique to work.
