Spinach and feta muffins

I adapted a Hugh Fearnley-Whernley recipe for these - and it turned out a treat.

Makes 12 enormous muffins, or lots and lots of fairy-cake sized ones. You'll need:

1 small onion, finely chopped
whatever spinach you have lurking at the bottom of the fridge, chopped
a little olive oil
half a pack or so of feta, cubed
250g self-raising flour
2 teaspoons baking powder
1/2 teaspoon bicarb of soda
a little salt (not a lot, as the feta's pretty salty)
2 eggs
80g butter, melted and cooled down a bit
200ml buttermilk (either use milk with a squeeze of lemon juice, or add 75g yoghurt to 125ml milk...)

Stick your oven on at about 200 degrees C, and line your muffin tin/cupcake tin with paper/silicon cases of your choice.

Fry the onion in a little olive oil, until it turns translucent. Add the chopped spinach, and stir for a couple of minutes until it's wilted. Take off the heat, and leave to cool.

Sling the flour, bicarb, baking powder and salt into a large mixing bowl. Whisk the eggs/buttermilk/melted butter together in a jug - and then pour them into the flour mixture. Mix everything gently together. Carefully fold in the onion/spinach mixture, and then the feta cheese.

Spoon the muffin mixture into your cases, and then bake in the oven for about 10-12 minutes (small fairy-cake size), or a 15-20 minutes (large muffin size) until golden.

Eat lots while hot. They'll keep for a while, but are loveliest warm.
