2 tablespoons butter
450g potato, diced into small 1/2cm dice
1 and a half Spanish onions, diced
6 eggs
3/4 teaspoon salt
1/2 teaspoon pepper
2 tablespoons of chives
2/3 cup of Gruyere or Emmental cheese
60ml of double cream
1 large Hass avocado diced (ripe, but still firm)
I adore frittatas. They are similar to Spanish omelettes but seem to be far more open to interpretation than the classic Spanish omelette which rarely deviates from the three main ingredients of potatoes, onion and eggs. Avocado seems to work really well in a frittata because of its wonderfully smooth texture. It is also delicious with chorizo and red peppers.
N.B. If you like you can add lardons of bacon to the potatoes when they are frying off.
