• Whisk the eggs in a salad bowl and add the milk, the butter, salt and pepper
• Pour the Tapioca on it and stir with a whisk
• Let the mix rest for 10 minutes
• Meanwhile, cut slices of ham and cubes of mozzarella into 1cm cubes.
• Mix the cured ham with the tapenade and with the first mix you made
• On a baking tray greased with butter, make buns of 2 cm of diameter with the mix, incorporate one mozzarella cube in each bun
• Brush a little egg yolk onto each bun
• Cook them in the oven at 180°C for 30 minutes

Suggestion:

• Instead of using ham and tapenade you can use smoked salmon and dill
• You can prepare the buns in advance and cook them when the time is right
