Cream butter and sugar in large bowl about 3 minutes until light and fluffy; beat in yolks, vanilla, and almond extract thoroughly.
Mix in flour and salt just until combined; do not overmix.
Roll into 1-inch balls; generously coat with sparkling sugar and place about 2 inches apart.
Make deep center indent with thumb or back of 1/2 teaspoon measure; gently smooth cracked edges.
Fill each with about 1/2 teaspoon raspberry jam.
