Pour the stock in a pot and bring to a simmer
In a large frying pan, pour 10 ml of oil and add the finely chopped onions, place on a low heat and cook until the onions are translucent. Then increase the heat and add the rice. Steer constantly, it is important that every rice grain is coated with the hot oil and toasted.
After about one minute, the rice will turn from white in colour to a translucent yellowish, now pour the wine and steer. Once the wine (and the alcohol) is evaporated add the first ladle of hot stock, basil leaves and the Bolognese sauce (you can find recipe for bolognese sauce by clicking the link) . Steer the rice regularly adding stock every time is drying up
After about 17-18 minutes the rice should be ready, it should be cooked but have still a bite in the centre. Decant on a large tray, spread thinly and let it cool as quickly as possible.
Once the rice has cooled down completely, place in a mixing bowl, add the grated parmesan. Mix the mixture well.
Divide the mix into 8 to10 bowls or alternatively use an ice cream scoops in order to have uniform size suppli.
In your hands, shape the suppli in the classic sub shape, force your finger in the middle creating a cavity. After the space is made, place the mozzarella strip inside and close pressing firmly.
Once all suppli have been formed prepare for the breading: place the flour and the breadcrumb in separate large bowl; break and beet slightly the eggs in a smaller bowl.
Firstly - one by one, roll the suppli in the flour.
Secondly - deep in the egg mix.
Thirdly - roll in the breadcrumb, making sure all the parts are covered.
Finally - rest the suppli in the fridge until you are ready to fry them.
If you have a fryer, set it up at 160 C or 320 F, alternatively use a deep large
pan and use a probe to control the temperature
Fry the suppli for 5/6 minutes mooing them and flipping often ensuring an even colour and crispiness is achieved.
Rest suppli on the kitchen paper towel to absorb the extra grease and oil before serving
