In one of our recent batches of scones, I added vanilla. I don't know why I didn't think of that before--it's delicious. I added it to the liquid, right before the final stir. The post on our favorite scone recipe is here. Oh, and I just made some lemon sugar and am eager to try some in our scones as well. To make lemon sugar, I just mixed the zest from one lemon with two cups of sugar and let it sit, covered. It took a couple of days for the sugar to take on a lovely, but delicate, lemony flavor. I think it will be fabulous in several recipes--the boys love anything lemon!
Hope you have a wonderful weekend,
Sandra
