As with most countries, the Dutch have a national anthem, dress and colour. The Dutch also have a National Milk. It is called Karnemelk.
How you make Karne milk is a mystery, but from what I have tasted, here is the method:
1. Take one carton of regular milk.
2. Leave it to stand at room temperature for 2 days.
3. Add cat vomit.
4. Break open one cockroach and pour in contents.
5. Stir with dirty finger in the clog of a tramp.
Serving suggestion: leave in carton.
The verb Karnen is the churn, which is exactly what it makes your stomach do.
