How do you make pesto sauce?
Traditionally pesto would have been made in a large pestle and mortar with each of the ingredients being added and pounded in turn until the right consistency was reached (the word pesto comes from the Italian word ‘pestare’ which means pounded). In modern recipes, a food processor is often used to speed things up.
Which ingredients are in pesto sauce?
The classic ingredients in pesto alla Genovese are basil leaves, pine nuts, garlic, Ligurian extra-virgin olive oil and Parmesan, Grana Padano or pecorino.
There are loads of variations on this original recipe. Other nuts such as walnuts, cashews and almonds are sometimes substituted for the more expensive pine nuts and using leaves like watercress, rocket and even kale in place of basil is also popular. Red pesto is actually a classic Sicilian recipe and is made with almonds and sun dried tomatoes. Vegan pestos use creamy cashews and brazil nuts to stand in for the missing cheese.
How long does pesto last?
Once made, fresh pesto is best used straight away, but will keep for a couple of days in a sealed container in the fridge.
