The last thing chefs want or need is three young children running through a working kitchen though, especially these particular kids.
I would what they, the whole family, eat on an everyday basis anyway? What is a normal Dutch family meal?
The King and Queen told that they love "healthy food", particularly fish. In an older interview, when asked about her cooking skills, the then Princess Máxima responded that the microwave was a great friend. That means that when the cook(s) are off duty, the family has an already prepared meal: only to be heated in the microwave.
A normal Dutch family meal is potatoes, vegetables and a piece of meat. But of course globalization has reached the Dutch kitchens too and there are Indonesian, Surinam and Caribbean influences, there is the Turkish and Moroccoan kitchen, there is the French, Spanish and Italian kitchen. I think the Dutch have internationalized very much. As so often: the more money you have, the better (healthier, more varied) food.
In my street there is a big organic supermarket. Everything sustainable, organic, biologic, animal-friendly and 'honest'. The prices burn a hole in your wallet but it is a success. However, the customers look like hipster chic, field hockey dudes, horseriding girls, pearl earrings ladies and red pantalon gentlemen. That sort of types. The lower the income, the more fat, the more saturated, the more frozen, the more junk the food is.
Queen Máxima once remarked she loved
Dulce Leche, an Argentinean treat. Her brother Martín has two succesful restaurants, one in a five-star hotel in the posh ski-resort San Carlos de Bariloche and one in Villa La Angostura, a small but very touristic and extremely expensive village near the Huelpi Lake in a National Park. (The King and Queen own two lots of land on a resort there, so they will probably frequent Martin's place to for a good meal). I have the idea that cooking skills are not too apparent with the King and Queen.
