I started making this pesto about 5 years ago and haven't bought any since - delicious!
Pesto
25 g. basil
20 g. parsley
85 g. Parmesan cheese
85 g. pine nuts
2 cloves of garlic
125 ml. olive oil
salt and pepper
Put all dry ingredients in food processor and slowly add oil till you get desired consistency. Adjust seasoning - I find it needs extra salt.
I don't use extra virgin oil and have used half sunflower oil and can't taste any difference. Also when short of pine nuts substituted a wholefood seeds mix.
Have kept this successfully in fridge for couple of months making sure it's topped up with oil after use.
Hope you enjoy!
