Preheat oven to 375°F. Position rack in top third of oven. Mix flour, 1 cup sugar, poppy seeds, baking powder, lemon peel, and salt in processor. Add butter and cut in, using on/off turns, until mixture resembles coarse meal. Whisk egg and lemon juice in medium bowl to blend. Add to flour mixture. Using on/off turns, process until moist clumps form. Add 1/3 cup milk. Using on/off turns, process just until dough comes together, adding more milk if dough seems dry. Using floured hands, gather dough into ball. Flatten into 8-inch round. Cut round into 8 wedges. Transfer scones to large baking sheet; brush with milk. Sprinkle with remaining 1 tablespoon sugar.
Bake until scones are golden brown and tester inserted into center comes out clean, about 25 minutes. Transfer to rack and cool
When I was done, I bagged up a couple for my friend Steph. . . she is such a good friend! I tied it with a red and white polka dotted gross grain ribbon and used my new stamp from the SU set Punch Bunch (it was part of the sale-a-bration promotion).
