This might seem silly, but I am sincerely interested; what refreshments and such are known in the old world and how common they are?
Tobacco: they have it, but is it only for the wealthy or for everybody? Is it expensive? Do they smoke it in pipes only or also in cigarettes?
Coffee: never heard they had it in the old world but it was consumed in the Mediterrenean in the 16th century already (or so I think) so do they have in Tilea maybe?
Tea: I always thought they had tea, but in Fell Cargo, Cpt. Silvaro wonders what the hell is "tee".
Ice cream: invented in the 17th century. They have Steam Tanks, so why not?
Chocolate: Spanish conquistadors drank hot chocolate as an energy drink. Maybe the exploring nations know it? I'd like to think elves had small chocolate shops. Would fit them, wouldn't it?
Potatoes: In G&F books there's potatoes, but there are also caribou in Kislev, which is as stupid as giraffes in Bretonnia. So, are spuds introduced yet?
Tomatoes: they were thought poisonous in the Medieval time. Do Old Worlders consume them?
Speculation? Real knowledge?
