One of the magazines used to carry a recipe page a while back, but that seemed to die the death once new young inexperienced journalists became the norm.
It has always been one of the 'wonders' of my life to know if anyone actually uses the 4 burner hob and oven that many of the mnaufacturers seem to think is essential. I have yet to see any test report with a kitchen in a caravan filled with 4 cooking pots on each burner and something roasting away in the oven. Storing all the items needed for such an exercise is also usually a missed topic. One journalist a few years ago let the cat out of the bag. The reason evidently the kitchens were never used was because the manufacturer wished them to be returned un - scorched or not looking as if they had been used as they wished to pass the van to another magazine for a write up. So there you are, the manufacturers know thes things look old rapidly.
In the last 2 years of continual caravanning I have only met one person who stated the oven in his van was a necessity. He needed it to warm the pies when he went on Rallies and there was no electric. Well, at least there was a genuine reason. Looking at the average 'delivery' of utensils at the communal washup point on CC and C&CC sites seems to suggest a distinct lack of culinary experimentation going on, unless the frying pan is essential.
Invariably around teatime on many campsites all you can hear is the repeated sound of 'ping' as the microwave in the awning does its stuff.
My own van has a 3 burner hob and we have yet to use all 3 at any one time, so why I would need 4 is a mystery. No oven or grill is present, as is our wish. Yet we manage 'Moules mariniere' quite easily., or nicely done steaks or even a good stir fry. Of course dishes such as casseroles, Italian dishes are all easily done in one pot. We also use a saucepan combination with a steamer part on the top so can do several vegetables at once and an electric frypan/griddle connected outside.. Of course the BBQ is always there if required, and very pleasant it is in the hot weather.
The 'on site' fish and chip van can range from 'excellent' to the greasy spoon. Maybe it is a matter of timing, I don't know. The best we have experienced so far is the one on the Broad Park CC site in Devon. Fabulous fish and chips, and even delivered direct to your van. What more could you ask for.
