Translation:One cinnamon roll and a glass of milk, please.
The algorithm is not as smart as that. It accepts a single wrong letter if it doesn't produce another meaningful word. It cannot reason that while 'cinammon' has two errors it is still easily understood. From the point of view of the algorithm, "cinammon" has similar errors as, say, "maaa" if you're trying to spell "mama" (one m missing, one extra a)
Korvapuusti is definitely a roll. The bun is what is normally referred to as "pulla" (though that's a very generic term which can be used for different shapes). The recipe for the dough is the same for both but for korvapuusti you roll it flat and fill it with sugar, butter and cinnamon then roll it, cut it to size and bake it.
