Put a pan on low heat and melt the butter.

Add the bacon cut in lardons (1/2cm x 3cm)

Mix until the bacon begins to brown

Add the milk cream

Mix occasionally until reduced

At low heat, add the grated parmesan cheese and mix continuously

Finally flavor the mixture with salt and pepper and turn off the stove

Immediately add 2 yolks and mix vigorously to avoid coagulation

Previously, in a pot, boil water with salt and add the spaghetti for 11-15 minutes

The sauce and the spaghetti have to be done at the same time.

Put the spaghetti on the sauce and mix carefully.

Serve with bread and if you want, white wine. Enjoy.
