Bechamel
Milk thickened with roux. Simple. Brutal in its honesty. If it's lumpy, that's on you.
These are the actual pillars. No derivatives. No "inspired by." Just the architecture.
Bechamel. Veloute. Espagnole. Hollandaise. Tomato.
You learn these not because it's fancy - but because they teach control. Fat. Liquid. Thickening. Emulsification. Reduction. Once you understand the system, you stop memorizing recipes and start composing.
