If you're someone who enjoys cooking with herbs and spices, you've likely used a mortar and pestle at some point. These kitchen tools have been used for centuries to grind and crush ingredients into a fine paste or powder. While they can add a unique depth of flavor to your dishes, you may be wondering if they're actually safe to use. In this in-depth guide, we'll take a closer look at mortar and pestles to determine whether they're food safe and explore some of the best practices for using them in your cooking.


Are Mortars and Pestles Food Safe?

The mortar and pestle is a popular kitchen tool for grinding herbs, spices, and other ingredients, but its safety can depend on the material it is made from. Traditional mortar and pestles are commonly crafted from materials such as stone, marble, granite, or ceramic, which are non-reactive to acidic or alkaline ingredients, making them generally safe for food preparation. Similarly, mortar and pestles made from glass, stainless steel, and wood are also considered safe for food use.

On the other hand, certain metal mortar and pestles made from materials like lead, steel, cast iron, copper, or zinc, can pose potential health risks. These metals may leach harmful chemicals into the food, rust, and react with acidic ingredients, thereby altering the taste of dishes. As a result, they are generally not recommended for use in food preparation.

To ensure that your mortar and pestle are completely safe to use, it is recommended to purchase from a reputable manufacturer that produces certified food-safe products. This certification indicates that the product has undergone testing and meets specific safety standards for food contact materials.

Now that you have learned about which mortars and pestles are safe to use, here is a detailed overview of each type, including their advantages and disadvantages, to help you select the best option for your needs:


1) Wooden Mortar and Pestles


Wooden mortar and pestles are ancient cooking tools that have been used in many cultures for centuries, especially in Asian cuisine. They are traditionally crafted from hardwoods like teak, oak, or maple and are valued for both their practicality and aesthetic appeal. 

The best part about wooden mortar and pestles is that they are lightweight and easy to handle. This makes them ideal for grinding small quantities of spices, herbs, and nuts, as well as for preparing pestos and other sauces. Additionally, unlike stone or ceramic mortar and pestles, wooden ones are less prone to chipping or breaking, making them more durable over time. 

However, because wood is not as hard and dense as stone or ceramic, wooden mortar and pestles may not crush the ingredients as finely. Nonetheless, this can be mitigated by using a larger wooden mortar and pestle or by pounding the ingredients in smaller batches.


2) Stone Mortar and Pestles


Stone mortar and pestles are often regarded as the most traditional and authentic type of mortar and pestle. These tools are typically made of materials such as granite, marble, or volcanic rock, and are highly valued for their durability and ability to grind ingredients to a very fine texture. Additionally, since they are typically heavier than wooden or ceramic mortar and pestles, they are more stable and less likely to move around during use. They are also resistant to scratches, stains, and odors, which makes them easy to cleanand maintain over time.

However, stone mortar and pestles can be more expensive than other types of mortar and pestles, and they may require some care to maintain their appearance and function. Despite these factors, the durability and high-quality grinding performance of stone mortar and pestles make them a popular choice for those who want a long-lasting and effective kitchen tool.


3) Ceramic Mortar and Pestles


Ceramic mortar and pestles are a popular choice for many cooks and chefs. These kitchen tools are typically made from glazed or unglazed ceramics, such as porcelain or earthenware. They are ideal for grinding spices, herbs, and nuts, as well as for preparing sauces and marinades. Additionally, because they are non-porous, these tools are easy to clean and do not absorb odors or flavors from previous uses. 

However, ceramic mortar and pestles can be more fragile than stone or wooden ones, and they may chip or crack if dropped or mishandled. The quality and craftsmanship can also affect their price, making them potentially more expensive than other types of mortar and pestles.


4) Glass Mortar and Pestles


Glass mortar and pestles are a newer addition to the market and have quickly become a popular choice for home cooks seeking a modern aesthetic. These tools are typically made from tempered glass or high-quality lightweight glass. Due to their material, they are easy to clean and do not absorb any flavors. Moreover, their transparency allows you to see the texture and consistency of the ingredients as you grind them, which can be advantageous when working with delicate ingredients like herbs or seeds. However, since glass can be more fragile than other types of materials, they are more susceptible to cracking or breaking.


5) Stainless Steel Mortar and Pestles


Stainless steel mortar and pestles are a popular choice for modern kitchens. These tools are typically made of high-quality stainless steel, which makes them durable, long-lasting, and resistant to rust and corrosion. They can also be used to grind acidic ingredients without the risk of staining or damaging the surface. Moreover, they are dishwasher safe, making them easy to clean and sanitize.

However, due to their smooth and non-porous surface, stainless steel mortar and pestles may not be the best choice for crushing and grinding certain tough or fibrous ingredients. In these cases, it may be necessary to use more force or switch to a different type of mortar and pestle.


Which Mortar and Pestle Should You Choose?

While they are multiple food-safe mortar and pestles out there, if you're searching for a versatile and durable option, a stone mortar and pestle, such as one made of granite, is worth considering. These tools are robust and heavy, making them ideal for crushing hard materials like peppercorns or seeds. They are also non-porous, which means they can be easily cleaned and sanitized, helping to maintain kitchen hygiene. Additionally, stone mortar and pestles are aesthetically pleasing, making them a great addition to any kitchen decor. Plus, the best part is that they are available in different sizes, shapes, and colors, allowing you to select the one that suits your needs and style.


How to Ensure the Safety of Your Mortar and Pestle

Maintaining safety in the kitchen is crucial, especially when using tools such as a mortar and pestle. To ensure the safe and efficient use of your mortar and pestle, it's essential to follow these tips:


1) Clean Thoroughly 


To keep your mortar and pestle in good condition, it's crucial to clean it thoroughly after each use. No matter what material your mortar and pestle are made of, warm soapy water and a scrub brush should do the trick. Be sure to rinse it well to remove any remaining soap and then dry it completely. Wooden mortar and pestles require extra care. Avoid soaking them in water and instead wipe them down with a damp cloth and dry them immediately after use.


2) Sanitize Regularly 


Sanitizing your mortar and pestle regularly is essential to maintain its cleanliness and prevent the spread of bacteria. There are a few ways to sanitize your mortar and pestle, including wiping it down with a vinegar and water solution or putting it in the dishwasher (if it's dishwasher-safe). It's important to check the manufacturer's instructions to ensure that your chosen sanitizing method is safe for the material of your mortar and pestle.


3) Avoid Overheating


To protect your mortar and pestle from damage, it's essential to avoid exposing them to sudden changes in temperature, which can be particularly harmful to materials such as stone and ceramic. Overheating these tools can lead to cracks, chips, or other damage that can affect their performance and longevity. If you need to grind hot ingredients, consider using a different tool that is designed for that purpose. This will help to ensure that your mortar and pestle last longer and remains in good condition for future use.


4) Avoid Cross-Contamination


Grinding various ingredients in the same mortar and pestle poses a risk of transferring flavors and odors from one ingredient to another. Thus, it's best to clean the mortar and pestle thoroughly between uses, especially if you're switching from pungent ingredients like garlic to delicate herbs like basil. It's also recommended to have separate mortar and pestles for different ingredients to avoid any contamination altogether. 


5) Check for Cracks and Chips 


Cracks or chips in a mortar and pestle can trap food particles, bacteria, and other contaminants, which can cause food poisoning and other illnesses. Additionally, small pieces of a cracked mortar and pestle can break off during use and end up in your food, posing a choking hazard.

To check your mortar and pestle for cracks and chips, inspect it carefully before each use. Run your fingers over the surface to feel for any rough or uneven areas. If you do notice any damage, stop using it immediately and dispose of it properly. Do not attempt to repair a damaged mortar and pestle, as this can compromise its structural integrity and increase the risk of contamination.


Best Practices to Follow When Using a Mortar and Pestle

To maximize the effectiveness of your mortar and pestle, it's important to adhere to these best practices:


1) Season the Mortar and Pestle


Before using a new mortar and pestle, it is recommended to season it to create a non-stick surface that makes it easier to grind ingredients and prevent food from sticking. To do this, grind a small amount of rice or salt in the mortar and pestle until it turns into a fine powder. Repeat this process several times until the powder is free of any debris. After seasoning, rinse the mortar and pestle thoroughly with warm water to remove any remaining particles. Lastly, make sure to dry it completely before using it to prevent any moisture from causing damage to the material. 


2) Use the Right Size


Using a mortar and pestle that is of the right size is crucial for the effective and efficient grinding or crushing of ingredients. Choosing the wrong size can lead to issues such as overcrowding or ineffective grinding. This can cause food to spill over and create a mess, making it difficult to work with. Alternatively, using a mortar that is too small can make it difficult to grind or crush ingredients, requiring you to repeat the process multiple times, which can be time-consuming. 


3) Use Gentle Pressure


When using a mortar and pestle, it's crucial to use gentle pressure and avoid over-exerting force. Over-exerting force can cause ingredients to fly out of the mortar, which can be messy and result in wasted ingredients. Additionally, using too much force can also cause the mortar to crack especially if it is made of delicate materials like glass. To avoid these issues, start by pressing lightly and gradually increasing the pressure as needed when grinding ingredients.


4) Hold the Pestle at the Right Angle


To use a pestle safely and effectively, it's important to hold it at the correct angle to avoid potential hazards. Holding the pestle perpendicular to the mortar can cause it to slip out of your hand and lead to injury. Instead, hold the pestle at a slight angle, and use a circular or grinding motion to crush or grind the ingredients. This technique allows you to maintain better control and apply the necessary pressure evenly, ensuring that the ingredients are ground or crushed uniformly.


5) Use the Right Pestle for the Right Mortar


While it is fine to mix and match your mortar and pestle, using the wrong one can cause damage to your tools. To prevent this, make sure to use the appropriate pestle for the type of mortar you have. For example, a wooden pestle may be better suited for a soft material such as ceramic, while a metal pestle may be better suited for a harder material such as granite or marble. 




The mortar and pestle is a timeless kitchen tool used for grinding and crushing a variety of ingredients. However, safety is of utmost importance when using these kitchen essentials, which is why it is crucial to purchase them from reputable manufacturers and follow the best practices when using them.
