Apple Crumble, well the french did like it when I started serving it so many years ago, that I cannot remember, but it became popular and I would see it in the shops in little tubs, if not big servings, so no, that is one thing I would take off my list.
And as soon as I saw of it's availability, I took it off my menu.
Marmite, love it or hate it, how could one tell, especially if looking at the jar, they might be forgiven for believing that it is a 'nutella' type substance??? Imagine the shock, I say this because I know of this happening.
Good english tea bags, with instructions on how to brew properly, so it would be proper tea, would be another suggestion, even the tissanes one buys in the UK don't just have the smell, but flavour too. How the french get away with the tissanes they sell is beyond me.
