Frequently Asked Questions

How long does shipping take?

U.S. orders ship from our U.S. warehouse and typically arrive in 2–4 business days. International orders ship directly from Thailand and usually arrive in 5–7 business days, depending on your location. You will receive a tracking number as soon as your batch ships.

Are the materials safe to use with food?

Yes. We use the highest-quality Thai granite, one of the strongest and most durable natural stones in the world. It is naturally non-porous and food-safe. Before cooking with the mortar and pestle, we recommend conditioning the granite surface to remove any residual stone particles and ensure an even grinding surface. We provide clear guidelines to do so with every order.

The cork base is impermeable. Cork trees produce suberin, a substance that makes cork naturally resistant to moisture, mold, and rot.

What is your return policy?

If you feel that our product did not meet your expectations, please return it within 30 days for a full refund. You can let us know in advance if you have any issues regarding any part of your KROK set, and we will make it right.

Mortar and Pestle FAQs

What is the best mortar and pestle for Thai cooking in 2026?

The KROK Handmade Thai Granite Mortar and Pestle is purpose-built for Thai cuisine. Handcrafted in Ang Sila, Thailand's granite capital, it features a 3-cup capacity for large curry pastes, a patented cork base to prevent slipping during heavy pounding, and an extra-long pestle that keeps your knuckles clear of the bowl.

How do you season a brand-new granite mortar and pestle?

Grind a handful of dry white rice in the mortar until it turns into a completely white flour with no gray specks — this removes loose stone particles. Discard the rice flour, then grind 5 peeled garlic cloves with a teaspoon each of cumin seeds, rock salt, and black peppercorns into a smooth paste. Discard this paste as well (it contains microscopic grit), rinse the mortar with warm water, and let it air dry. Your mortar is now cured and ready for cooking.

Is a mortar and pestle better than a food processor?

Yes — if you care about flavor, aroma, and texture. A food processor uses rapidly spinning blades that slice ingredients into small pieces, which generates heat and leaves many aromatic cell walls intact. A mortar and pestle crushes and smashes those cell walls completely, releasing more essential oils and creating a naturally emulsified, textured paste that blades cannot replicate.

What size mortar and pestle do I need?

For most home cooks preparing sauces, curry pastes, or multi-ingredient spice blends, a mortar with at least a 3-cup volume is ideal. Anything smaller risks ingredients flying out as you pound. If you only plan to grind single spices occasionally, a compact 6-ounce mortar will suffice, but a larger bowl is the better first purchase since it handles both small and big tasks.

Can you put a mortar and pestle in the dishwasher?

Never. The porous stone absorbs detergent chemicals and can retain soapy scents permanently. Dishwasher heat and harsh jets can also damage the stone surface and any cork or wooden components. Always rinse with warm water, scrub lightly with a brush if needed, and air dry completely.

How do you clean a granite mortar and pestle after use?

Rinse immediately with warm water and scrub with a stiff brush to remove residue from the pores. Use only a tiny amount of mild, unscented soap if you made an oily paste — then rinse thoroughly. Avoid aggressive chemicals and never soak the stone. Let it air dry completely before storing. If lingering odors persist, grind a small handful of dry rice and baking soda, then rinse.

What is the difference between granite and marble mortar and pestle?

Granite is harder, more durable, and acid-resistant, making it ideal for heavy-duty pounding, curry pastes, and acidic salsas with tomatoes or citrus. Marble is more brittle, stains permanently from acids, and can chip under hard smashing, but it excels at gentle emulsification for delicate sauces like pesto when paired with a wooden pestle. For a first purchase, granite is the more versatile lifetime tool.

How long does a granite mortar and pestle last?

A quality granite mortar and pestle is a generational kitchen tool. Dense, non-porous Thai granite does not wear down, crack, or degrade under normal kitchen use. With proper cleaning and occasional re-seasoning, it can easily last 50+ years and be passed down.

Why does my new mortar and pestle have grit in it?

All natural stone mortars have a slightly gritty surface straight from the quarry. Tiny loose particles remain in the pores until the bowl is properly cured. This is completely normal and exactly why seasoning with dry rice is mandatory before first use. Once cured, the surface smooths out and no additional grit will enter your food.

What can you make in a mortar and pestle?

A mortar and pestle is far more versatile than most people realize. Common uses include: Thai curry pastes, Italian pesto, Mexican guacamole and salsas, Middle Eastern hummus and za'atar, Argentinian chimichurri, French aioli, Indian spice blends and garam masala, compound butters, flavored salts, salad dressings, marinades, and even medicinal herbal salves.
