I will die on this hill: a blender does not make sambal. It purées. Pounding bruises — it tears cell walls, releases oils, and layers flavor in a way spinning blades never will. The first time you pound your own rempah (spice paste) and smell what comes off it, you'll understand why every serious Southeast Asian kitchen has a stone in the corner.

Here's how to pick one that lasts a lifetime.

Granite — the all-rounder (buy this one)

Heavy, rough-textured, unstoppable. Granite grips whole spices and fibrous aromatics — lemongrass, galangal, dried chilies — and grinds them to paste without skating around. It's the default for a reason.

Get a large one (6 inches / 2+ cups). Small mortars send chili flying and force you to work in annoying batches. Weight is a feature here, not a downside — the heavier it is, the less it walks across your counter.

Thai clay-and-wood — for som tam and soft work

The tall clay mortar with a wooden pestle is built for pounding, not grinding — bruising garlic and chili, then tossing in green papaya for som tam. Lighter, taller, gentler.

If you love Thai salads and light pastes, this is a lovely second mortar. It's the wrong tool for hard dry spices, though — that's granite's job.

Molcajete-style volcanic stone — the crossover

Basalt mortars (yes, the Mexican molcajete) work beautifully for wet spice pastes too. If you already own one, you're set.

Break it in before first use

Raw stone sheds grit. Season it so your first sambal isn't crunchy in the wrong way:

1. Pound a handful of raw rice to powder. It'll come out grey.
2. Discard, rinse, repeat until the rice powder stays white — usually three or four rounds.
3. For extra measure, grind a little garlic, salt, and cumin and rinse.

Now it's ready. Never use soap long-term (stone is porous and holds it); just rinse, scrub with water, and air-dry.

What to make first

Start with a simple sambal: pound dried chilies (soaked), shallots, garlic, a little belacan, and salt into a rough paste, then fry it in oil until it darkens and the kitchen smells illegal. Spoon it over rice, noodles, eggs — anything.
