Cottage cheese made of sheep milk has a great, very distinctive taste. We usually eat it with gnocchi and bacon, but it works really well with mushrooms, too. If sheep cottage cheese is not available in your country, use a mixture of feta and sour cream or ricotta and sheep cheese. Or goat cheese with something that will make it more creamy. Maybe you will find sheep cheese as pecorino, and sheep cottage cheese as ricotta di pecora, as the Italian versions may be more widespread.
