How to Use a Mortar and Pestle: A Beginner's Guide to Spices, Herbs and Pastes

There are two kinds of people in the kitchen: those who see a mortar and pestle and immediately think of fragrant spices, homemade curry pastes and impressive cooking skills, and those who look at it and think, “Beautiful. But what exactly am I supposed to do with that?”

If you fall into the second group, welcome. The mortar and pestle is one of the simplest tools in the kitchen, but it can completely change the way you cook. It does not need batteries, complicated settings or a 14-page instruction manual. Give it some spices, herbs or aromatics and a little elbow grease, and it gets to work.

The real secret is learning how to use it.

 

It is not just a tiny bowl with a heavy stick

A mortar and pestle has two parts. The mortar is the bowl, while the pestle is the handheld tool used to crush and grind whatever you put inside.

The shape matters. A good mortar gives ingredients enough room to move while the pestle presses, crushes, and grinds them against the surface. This makes it particularly useful for ingredients that are difficult to process evenly with a knife.

Whole spices are a perfect example. Crushing coriander seeds, cumin, peppercorns or cardamom just before cooking releases their aroma and flavour. Instead of opening a jar of ground spice that has been sitting in the cupboard for who knows how long, you are working with something freshly crushed.

And yes, your kitchen is about to smell significantly better.

 

Crushing is not the same as grinding

This is where beginners often go slightly wrong. You do not always need to pulverise your ingredients into powder.

For spices such as peppercorns or coriander seeds, start by pressing and twisting the pestle. For larger or harder ingredients, use a gentle pounding motion first to break them down, then grind them until you reach the texture you want.

Fresh herbs require a different approach. Rather than aggressively smashing them into oblivion, press and bruise them against the mortar. This helps release their oils while keeping some texture.

The same principle works beautifully with garlic, ginger and chillies. Crush them together, add a little salt, and you can quickly create a rough paste packed with flavour.

 

Your easiest homemade flavour paste

Want to make a simple paste without getting out the food processor? Start with garlic, ginger, fresh chilli and a pinch of salt.

Place the ingredients in the mortar and begin with a few gentle presses. As they soften, work the pestle in a circular motion, scraping the mixture from the sides and bringing it back towards the centre.

Keep going until you reach your preferred consistency. A chunky mixture works well for some marinades and sauces, while a smoother paste is useful when you want the ingredients to disappear into a dish.

You can also add fresh herbs, spices, lemon zest or other aromatics depending on what you are cooking.

 

A little technique goes a long way

The biggest mistake you can make with a mortar and pestle is trying to process too much at once. If the mortar is overflowing, the ingredients will escape around the sides rather than being crushed properly.

Work in smaller batches and let the weight of the pestle do most of the work. You do not need to attack the spices as though they personally offended you.

It is also worth paying attention to texture. If you are making a spice blend, you might want something fairly fine. For a salsa, marinade or herb mixture, leaving some texture can make the finished dish more interesting.

 

What can you make with one?

Quite a lot, actually. Fresh pesto is an obvious favourite, particularly when you want to create a more rustic texture. You can also use a mortar and pestle for curry pastes, guacamole, spice blends, marinades, salad dressings and herb sauces.

It is particularly useful when you want to release the oils from fresh herbs and spices rather than simply chopping them. That extra crushing action can bring out aromas that you might not get from a knife alone.

Once you get comfortable using it, you may find yourself reaching for it far more often than expected.

 

Final thoughts

A mortar and pestle is a reminder that good cooking does not always require complicated equipment. Sometimes, a bowl, a sturdy pestle and a handful of fresh ingredients are enough to turn an ordinary meal into something far more aromatic and flavourful.

Start with something simple. Crush a few peppercorns. Make a garlic and herb paste. Try freshly ground spices in your next curry. Before long, that mysterious object sitting quietly in the kitchen will become one of the tools you reach for without even thinking.
