Heres a good one to impress that's not too hard, carbonara (made properly with eggs, not cream).
You need; fettucini, eggs, spring onion, garlic, cracked pepper, bacon, mushrooms, fresh grated parmesan, parsley, onion.
Heat a large pot with plenty of olive oil for the pasta (fettucine tends to stick) and salt it lightly.
Fry the onion, mushies and bacon (in that order) in olive oil.
In a large bowl place a couple of eggs, garlic, parsley, chopped spring onion (diagonally is good) and cracked pepper. Whisk it (fork will do) and then add a couple of handfuls of the cheese (I never measure anything).
When the pasta is cooked, drain it in a colander quickly and then put it back in the pot you used. Throw in the rest of the ingredients and stir until the cheese is melted (the heat from the pot should do that & cook the egg slightly).
Serve immediately - YUMMO!
