Step 1:
Heat that pan and put some chopped bacon in it. No need for butter or oil, bacon is greasy as hell. Step 3:
when cooked and brownish, add cream until you cover it. Step 5:
then add cheese slices until you think "damn, that’s too much cheese". Step 7:
let it melt and then add half or the whole cube of meat stock, depending on the quantity of sauce you made. Step 9:
just keep adding and tasting until it’s delicious and maybe a little bit salty. (when you mix it with the pasta, the flavour tones down) Step 11:
hh, and i forgot: don’t forget to heat cook your pasta before you start the sauce. Or you’ll end up eating the sauce with a spoon. I’ve done it. Step 13:
i usually start making the sauce when the water is boiling and i’ve put in the spaguettis. But don’t trust it, sometimes it just becomes soft. Too soft. Baby butt soft.
