Add all the ingredients into a food processor (leave the chives out for now) and blitz/blend (but don’t over-mix!).
Add the chopped chives and mix with a spoon.
Pour the batter into a muffin tin and bake in static oven at 180C for 20 minutes (I have used muffins cases to make it easier to remove afterwards but you can also grease the muffin tin and pour straight into it).
