You answered my question exactly.
Biscuits in my world are made from a rolled flour dough made with yeast or baking soda, and cut into about 2" rounds before being baked. They are not sweet but they're very good. Usual uses include being eaten with a bowl of chili or soup, or chicken with gravy, as a side to a salad, or as a starch substitute with just about any routine American dinner. Best if served warm with butter.
American (non-Internet) cookies are in the dessert category.
What do the British mean when they say biscuit?
A biscuit is similar to a cookie but we have loads of different ones plain ones sweet ones like shortbread some have cream in them like aeros I think that is what you call them? but they are alway crisp. One of the most popular are choclate digestive which is a wheat crisp biscuit with milk or plain choclate on top. Thre are literally abut 30 or forty different flavours type makes.
Biscuits in England are normally served with a cup of tea in some resturants you get coffee with a little sacket of crisp biscuit in it you probabably get that in the states as well as I have seen this in Europe as well with coffee.
Your biscuits are similar to our scones which we serve at a tradition English high tea with jam (jelly - jelly in England is your Jelo or jam made without skin or pips and sieve before putting into the jar) and fresh double cream.
