Knead all ingredients, up to the egg yolk, into a dough. Chill for about 30 minutes. Then roll approx. 40 cherry-sized balls out of the dough. Roll the balls first in egg white and then in the chopped pecans. Spread the balls generously on two baking sheets lined with baking paper and use the handle of a wooden spoon to make a small indentation in each ball. Put 3-4 teaspoons of raspberry jam in a freezer bag and cut off a small corner. Inject a dab of jam into each well.
Bake at 180 ° top / bottom heat for approx. 15 minutes.
