This is a very simple and lazy cheese dip and it tastes just divine! Just add some finely grated cheese to creme fraiche and enjoy! You can use different cheese for different tastes - blue cheese is delicious but a mix of cheddar and Parmesan is more kid friendly (to most kids - mine love Stilton - definately my kids!).
You can add extras - like onion or chives. Or leave out the cheese and add garlic and dill. All good!
