To venture into a supermarket in a foreign country is not the tedious flog round that doing Tesco, Sainsbury’s or Morrison’s is at home in the UK [or Walmart, Intermarché, Netto or Dia for citizens whose countries sport those stores]. It is more an exploration of unknown territory and requires a little bravado, some imagination and a leap of faith.

I suppose every nation must have store cupboard items without which life would become sad. Do the Germans take sauerkraut wherever they travel? Must the Spanish transport a large, cured ham with them? Perhaps the French stow away a stash of truffles? Who knows? I can only let you into the secrets of the travelling British; the food and drink necessities without which we would feel impoverished:

• Of course! We are British! Decent tea is impossible to buy abroad. I’m sorry, European neighbours-but ‘Liptons’ does NOT cut it. We take a huge supply of strong, ‘Yorkshire’ tea bags; 2 cups every morning=bliss! We drink it with a little milk. No other nation understands this.
• Tomato ketchup. It is relatively easy to get this in most countries-but I like to be sure. A bacon butty is a camp-site morning staple.
• English mustard-hot and strong. Great for sandwiches or cooking. Foreign mustards can be good but are not the same as English.
• Mixed herbs. They are versatile. You can’t take every individual herb in a camper-van. There are space constraints, likewise-
• Curry powder
• Tomato puree
• Garlic paste
• Stock cubes. I take beef Oxo, chicken Oxo and vegetable cubes, plus Bisto and flour.
• A variety of tins, including tomatoes, peas, lentils, sweet corn. These must be replenished during trips although substitutes often become necessary.

Armed with these items we must then plunge into the mysterious world of whichever grocery store has us at their mercy. Meat or fish is required, plus vegetables-fresh if possible. In Scandinavia we are able to recognise some of the meat by various methods but not the names. ‘Skingke’ sounds like some kind of primeval eel-shaped fish, but turns out to be ham. Pork looks familiar, as does chicken. A pack of beef is easily identified by being roughly the price of a small car and also called ‘biff’. There is chicken [‘kykling’] but since we don’t transport a chest freezer around with us for bulk buys it isn’t an option. We can purchase two pork chops from the meat counter. Hooray! Pork it is then.

I’ve gained a new respect for fresh, British fruit and vegetables now I’ve seen the price of cabbage or lettuce in Scandinavia. We are cautious, reigning in our usual gung-ho approach to greengrocery buying and becoming selective. We’ve seen enough burgers, pizzas and hot dogs during the last three weeks in Northern Europe to supply the fast food joints of Disneyland for several years.
