I have seen both words used in the sugar cone recipes, the former being slightly stiffer and the latter being more liquid. Anyway, the text doesn't call for a cookie or a biscuit, but for the dough that is shaped and colored in the form of rose petals, frozen and then covered with more dough....I don't think you could do this with uncooked batter. In any case, I think you do want to use the word "batter" or "dough" in this particular translation. In this reference the two words are used interchangeably in the same recipe:
