Put all the ingredients into a food processor bowl
100 g wild garlic, 50 g onion, 50 g walnuts, 200 ml olive oil, 50 g parmesan, ½ tsp salt, ½ tsp sugar
Whizz everything together until smooth and a little emulsified
If you don’t have a food processor, chop everything finely, then bash it all together in a pestle and mortar, or a big bowl using the end of a rolling pin
Store in a jar in the fridge for up to 2 weeks, or freeze
Notes
you could use any nuts, pine nuts, Brazil nuts, almonds or peanuts, or anything else.
or I none at all to keep the cost to a minimum or to create a nut free version
use any allium. So leek, shallots, spring onions, red or white onions
change the parmesan to cheddar
if push came to shove, I bet it would still taste good using just cheap cooking oil and the garlic, and nothing else.
