Pesto alla Genovese is a traditional Italian basil pesto based on basil, pine nuts, parmesan, pecorino, garlic and olive oil. It can be used in a number of dishes and takes minutes to prepare.
Crush the garlic clove with the salt in the mortar and pestle.
Once creamy, add the pine nuts and pound until you get a smooth paste.
Add the basil leaves and continue to crush, working from the edges to the middle of the mortar.
Once the basil is incorporated add the grated parmesan and pecorino and crush until combined.
When the pesto is smooth (or slightly chunky if you are wanting a chunkier pesto), pour in the oil and slowly pound with the pestle until just combined.
Test for seasoning and use in your favourite pesto dishes!
Notes
You can use a mini food processor instead of the traditional mortar and pestle, and pulse the ingredients lightly, being careful not to chop them too much at a high speed as this can cause the basil to taste bitter.
I have made this recipe with both the mini food processor and pestle and mortar, and although the latter is slightly more work, the taste is superior so I would recommend making it in a mortar and pestle, if possible.
To use pesto with pasta: stir the pesto through warm al dente pasta, adding a little of the pasta cooking water if it is too thick.
Don’t try making pesto with only pecorino – it is far too salty! I speak from experience 😉
The pesto is best used soon after making, however if you want to store leftovers, place in a small airtight container with a narrow opening and pour oil over the top of the pesto to completely cover the surface. Store in the fridge for up to 2 days. The top may brown slightly as the air gets to it, however if you gently spoon that off you will be left with bright green pesto underneath.
