In the world of cooking, tools play a crucial role in transforming raw ingredients into delicious meals. One such tool is the stone mortar and pestle, a timeless kitchen essential used for crushing and grinding spices. But are stone mortar and pestle sets safe for your culinary endeavors? In this blog, we will delve into the safety aspects of using stone mortar and pestle, addressing concerns and providing valuable insights.

The Basics of Stone Mortar and Pestle

A stone mortar and pestle consist of two components: the mortar (a bowl) and the pestle (a club-shaped tool). These tools have been used for centuries across cultures, offering a sturdy and effective means to crush, grind, and blend ingredients. They are traditionally made from various types of natural stone like granite, marble, or basalt. Below we will go over each of these material one by one:

1) Thai Granite Mortar and Pestles

Granite is a popular choice for mortars and pestles because of its hardness and durability. Its non-porous surface ensures that it does not absorb flavors or odors. But care must be taken to choose a well-finished product, as a rough surface might trap food particles.

2) Marble Mortar and Pestles

Marble mortars are made from a softer stone, which makes them easier to work with. These mortars are excellent for grinding softer herbs and spices but might react with acidic ingredients. They are also more susceptible to staining.

3) Basalt Mortar and Pestles

Basalt is a hard volcanic rock often used in traditional Asian cooking. It has a rough texture that's great for grinding but requires proper seasoning to prevent food particles from getting trapped.

4) Other Natural Stone Mortar and Pestles

Other stones like limestone or agate are also used in mortar and pestle sets. Each of these stones has specific characteristics, and it's essential to research the particular stone to understand its safety and functionality.

Benefits of Stone Mortar and Pestles

Stone mortar and pestles hold a revered place in kitchens across cultures, cherished for their unique advantages that contribute to elevated culinary experiences. Below, we will explore the multifaceted benefits these traditional tools bring to your cooking endeavors:

1) Enhanced Flavors

One of the primary benefits of using stone mortar and pestles is the way they interact with ingredients. The rough surface of the mortar and the grinding action of the pestle help release essential oils and flavors from herbs, spices, and other ingredients. This can lead to more vibrant and intense flavors in your dishes.

2) Control Over Texture

Stone mortar and pestles allow for precise control over the texture of your ingredients. Whether you're looking for a coarse grind or a fine powder, these tools let you customize the consistency according to your recipe's requirements.

3) Longevity and Aesthetics

Stone mortar and pestles are not just functional tools; they are also aesthetically pleasing additions to your kitchen. Crafted from durable natural materials, these tools can withstand the test of time when properly cared for.

Are Stone Mortar and Pestles Safe to Use?

Yes, stone mortars are generally safe to use. But there are a few things you need to be aware of:

Choose the Right Stone: Opt for high-quality, food-grade stones that are non-porous to ensure safety and avoid potential contamination. For a uniform grinding experience, opt for a large mortar that has an evenly round bowl shape.

Season the Mortar and Pestle:Before using a new stone mortar and pestle, it's advisable to season it. This involves grinding rice or other grains to remove any potential residue or loose particles from the manufacturing process.

Clean After Every Use: Proper cleaning is essential to maintain the safety of stone mortar and pestles. Wash them thoroughly after each use to prevent the growth of bacteria or mold. After cleaning, ensure that both the mortar and pestle are completely dry before storing them.

Alternatives and Modern Options

While stone mortar and pestles have their unique charm and benefits, the world of culinary tools offers a range of alternatives and modern options to suit various preferences and needs. Let's explore some of these alternatives and how they compare to the traditional stone mortar and pestle:

1) Ceramic and Steel Mortar and Pestles

If you're looking for an alternative that addresses concerns about potential flavor retention, ceramic mortar and pestles or even stainless steel mortar and pestles are a worthy consideration. Unlike porous stone surfaces, ceramic and stainless steel options are non-porous, making them less likely to absorb flavors and aromas from ingredients. This characteristic allows for versatile use without the worry of residual tastes impacting the next batch of ground ingredients.

2) Electric Spice Grinder

For those who prioritize convenience and time efficiency, electric spice grinders offer a modern solution. These appliances are designed to efficiently grind spices, herbs, and other ingredients with minimal physical effort. However, it's important to note that electric grinders might not provide the same level of control over texture and flavor extraction as traditional mortar and pestles.

3) Blenders and Food Processors

Blenders and food processors are versatile kitchen appliances that can handle a variety of tasks, including grinding. These modern options are particularly useful when working with larger quantities of ingredients or when a finer texture is desired. However, similar to electric spice grinders, they might not provide the same tactile engagement and precision as manual stone mortar and pestles.

4) Wooden Mortar and Pestles

Wooden pestles are made from pine nuts and provide a natural and rustic alternative to stone counterparts. While wood is porous, regular seasoning and proper cleaning can help maintain their hygiene. Wooden pestle tools offer a softer grinding surface compared to stone, which can be advantageous when working with delicate ingredients that require gentle grinding.


Stone mortar and pestles are safe kitchen tools when used correctly and maintained properly. By following the safety considerations and usage practices outlined in this blog, you can harness the benefits of these tools while ensuring the safety of your kitchen creations.
