batter mix to make yorkshire puds! I know you can make it with flour and other stuff but I feel it doesn't have the same taste when you use batter mix.
Anything by cadbury. yorkshire tea bags. super noodles. spaghetti with those little sausages (though they might be a bit heavy?) wotsits/quavers/skips. angel delight. mr kipling bakewell tarts (or anything mr kipling). lemon curd.
shame you couldn't send something like bread, hovis is to die for. so soft and yummy (bread here is like stone).
