50g of pine nuts, these are traditional, but if preferred you can use hazelnuts, almonds, pistachios, walnuts, or any other nuts you find lurking in the kitchen cupboards
80g of vegetable tops, you can use all of one, a mixture of some, or add in some soft herbs (like basil or parsley) if you don’t have quite enough
1 small garlic clove, crushed
30g of Parmesan, grated (use a similar cheese using vegetable rennet if serving to vegetarians)
extra virgin olive oil, you'll need 5–7 tbsp depending on the veg tops used
salt
pepper
lemon juice
1 pinch of sugar
Method
1
Very lightly toast the nuts – you don’t want them to go too dark, or the pesto won’t be creamy
2
Blitz all the ingredients together in a food processor and taste for seasoning, adjusting if necessary. Alternatively, you can pound everything into a rough paste in a pestle and mortar
3
I always like to add a generous spritz of lemon to liven up my pesto and have found a small pinch of sugar nicely rounds out the slight bitterness found in some veg tops, but this is personal taste territory, so taste before adding
