Instructions
Heat oven 375F. Spray the molds of a 12 to 20-piece madeleine pan with no-stick baking spray.
In small bowl, whisk flour, salt and cream of tartar; set aside.
In food processor, pulse sugar, thyme and zest until uniform.
In a medium bowl, beat butter and sour cream until light and creamy.
Add sugar mixture; blend well. Add eggs, lemon juice and extract; blend well.
Add flour mixture; mix just until blended.
Spoon batter into molds until even with rims.
Bake 8 to 10 minutes for small madeleines (10 to 12 minutes for larger ones) or until edges are just golden brown and cakes feel firm when touched with the tip of your finger.
Immediately invert madeleines on to a cooling rack.
Cool madeleines completely before dusting with powdered sugar.
Notes
* To make cake flour: measure out ½ cup of all-purpose flour then remove 1 tablespoon of flour from that half cup and return it to the flour sack. Add 1 tablespoon of cornstarch to your measured flour, whisk and presto you now have cake flour.If you don't like thyme just leave it out.
