It’s not always restaurants get pesto right. Not that they don’t know how to do it – because it’s pretty straight forward. But it’s probably because restaurants here are used to making pasta ‘sauces’ quite creamy. So they add a load of cream in their pesto and call it ‘pesto sauce’. That’s certainly not how I like my pesto. There’s nothing snobbish about it. Basil tastes great when it’s not cooked and diluted with cream. Just some cooked pasta tossed in pesto enough to coat it is perfect.
