200 g pancetta diced and fried until crispy (bacon)
30 g oil saute onions 4 min/Varoma/speed 1
360g Ricotta (yogurt cheese)
360 g sour cream (creme fraiche)
4 eggs, salt and pepper
1 tsp caraway seed
*be careful with the salt depending how salty your pancetta or bacon is.
Put onions in separate bowl and let cool down

I had filling leftover so I made a simple whole wheat dough and spread it on top.
