Not too sweet. From the 1964 edition of Joy of Cooking, which describes them as a sophisticatedly flavored soft tea cookie with an oil base, a description I found quite accurate (to my surprise - I'd never thought of anything involving carrots as particularly sophisticated). I used whole wheat pastry flour and canola oil. I did not add any fruit, and I added ginger to half the batch - I liked them slightly better with it, but they were good without it too. I think these would also be good with nuts added, and if you do want them sweeter, you could make a glaze with confectioner's sugar, a little orange juice, and possibly a bit of butter or cream cheese. I like them as is. Cooking time includes cooking the carrots and zesting the oranges.
