For traditional Pesto Genovese, the Consorzio del Pesto Genovese recipe specifies a marble mortar and wooden pestle. Its recipe gives a clear hand-grinding sequence: pound garlic with coarse salt, add pine nuts, work basil in gradually with a gentle rotary motion, then mix in the cheeses and olive oil. A suribachi is also a hand mortar, but its maker documents the grooved ceramic surface for tasks such as sesame, ginger and dressings. If the traditional recipe is your aim, choose marble; if you already own a suribachi, use it for a recipe that suits its size and your preferred method.
Make the batch in stages
The Consortium’s English recipe gives ingredient amounts for a pasta batch. Wash and dry the basil first so it is ready before grinding. In the bowl, pound garlic and coarse salt to a cream, then add pine nuts. Add basil a little at a time and use a sustained circular grinding motion rather than hard straight-down blows. Finish by incorporating the grated cheeses and adding olive oil gradually. Staging the ingredients gives you room to work the leaves into the mixture instead of filling the bowl all at once.
The recipe specifies marble and wood for its traditional method. It does not make that tool a requirement for every basil sauce: the Consortium notes that people also use a blender today. Choose the hand-ground method when you want to follow the recipe’s specified process; use a powered method if that better fits your routine.
Choose the bowl by its inside space
Use the recipe batch as your starting point, then compare the mortar’s inner diameter, depth and stated capacity. The outside diameter alone can hide a narrow working bowl. Leave enough room to turn the pestle and add ingredients in stages. Stability matters too: the bowl should sit securely while you work, and its listed weight should suit how you lift and wash it.
For scale, Bembo lists one 20 cm Carrara marble model with a 13 cm internal diameter, 9 cm depth, 0.85 L capacity and 5.1 kg weight. Those are specifications for that model, not a universal size recommendation. A wide outside measurement does not tell you whether a different bowl has the same working capacity.
| Your kitchen task | Tool choice | Check before you start |
|---|---|---|
| Follow the traditional Genovese recipe by hand | Marble mortar and wooden pestle, as specified by the Consortium | Inner dimensions, bowl capacity, stable base and listed weight |
| Grind sesame or ginger, or mix a dressing | Suribachi and surikogi; OUJIGAMA documents these jobs for its grooved ceramic bowls | Maker’s size guidance, pestle fit and room to mix the finished amount |
| Make more than a small bowl can comfortably hold | Choose a bowl with more working room or divide the batch | The recipe’s batch amount and the tool’s stated capacity |
OUJIGAMA’s size examples are task-based for its own range: 11–12 cm for small amounts such as sesame or condiments, 15–18 cm for nuts or dressed vegetables, and larger bowls for family portions or bigger quantities. Use those examples to understand the maker’s sizing logic; they are not a direct capacity conversion for the Consortium’s recipe.
If your recipe does not specify a traditional method, a suribachi you already own can serve as your hand mortar when its maker’s instructions and capacity fit the batch. For the suribachi’s grooves, motion, size examples and care, see our suribachi and surikogi guide. For other Japanese cooking tools, visit the kitchen tools guide.
