Pour in the yeast water and mix together to form a dough.
You can use a stand mixer with a dough attachement to knead the dough, or do it by hand for 10 minutes.
Create a round ball with the dough and place it on a flat, floured surface and allow it to rest while you prepare the filling.
Chop the salami and cheese into small chunks.
Set aside about 80g of the dough for later and mix the fillings into the rest of it.
Roll the dough into a log shape and arrange in a 20cm / 8 inch ring pan, with a hole in the middle. If you do not have one of these, you can use a normal cake tin with an empty metal can in the middle.
Place the whole eggs with the shells on evenly spaced apart, vertically in the top of the dough.
Roll the excess dough into little logs and use these to cage and seal the eggs in a cross shape into the top of the bread.
Brush the dough with the melted butter and cover with a clean cloth.
Leave to rise for 1-2 hours in a place at ambient room temperature.
Preheat the oven to 180C
Uncover the casatiello and bake in the hot oven for 1 hour until golden brown.
When ready, remove from the oven and allow to cool in the tin.
Once cooled, gently remove the bread from the tin and serve.

Recipe Notes
Store the Casatiello in an airtight container for 3-4 days or in the fridge to prolong it for up to a week.
Serve with Easter chocolate, butter and extra salami.
You can try different fillings if you wish, Scamorza, Provola or Cheddar work well.
Allow the dough enough time to rise. It may take a little longer or a little less depending on the temperature and humidity when you make it.
You can omit the eggs if you'd prefer.
Baking can be slightly longer in some cases, up to 75-80 minutes. If it's getting too brown, simply cover the tope with foil and continue baking.
