First I’m going to show you an easy recipe for making pesto and then
I’ll give you some ideas on how best to use it, instead of just having
it with pasta all the time. When it comes to making pesto, you can
invest in a good processor if you like, but you can also make it using
a pestle and mortar. If you have a blunt blade from your processor then
don’t chuck it, but keep it specially for making pesto or marinades
where you need to bruise out the flavour, instead of chopping. You may
think it’s nice to toast the pine nuts until they’re coloured, to give
them a nutty taste, but the really good pestos I’ve tasted in Italy
just have them very lightly toasted, to give a creaminess rather than a
nuttiness. Pesto is normally made with green basil, but purple basil
looks good if you can get hold of some. Another way, slightly more
American, uses rocket instead of basil – it’s fragrant and interesting
with roasted meats, but I prefer this classic pesto recipe.
Pound the garlic with a little pinch of salt and the basil leaves in a
pestle and mortar, or pulse in a food processor. Add a bit more garlic
if you like, but I usually stick to ½ a clove. Add the pine nuts to the
mixture and pound again. Turn out into a bowl and add half the
Parmesan. Stir gently and add olive oil – you need just enough to bind
the sauce and get it to an oozy consistency.
Season to taste, then add most of the remaining cheese. Pour in some
more oil and taste again. Keep adding a bit more cheese or oil until
you are happy with the taste and consistency. You may like to add a
squeeze of lemon juice at the end to give it a little twang, but it’s
not essential. Try it with and without and see which you prefer.
