Do, Europeans like Catsup?

I lived in Europe two years. The reason they ate mayonnaise on French fries (they did not call them this) was because it did not get hot enough to grow tomatoes then. I suppose they have hot houses now, but probably still prefer mayonnaise. So do I. I say 'ketchup.' Mayonnaise and ketchup mixed together is what I used for salad dressing when my kids were small. They love that dressing in Sweden, but buy it already made. More expensive.

That depends... Are we talking tomato or curry ketchup here? Because I like both.

They love it on their 'Chips' (our fries)
