Bird's Nest Cookies

INGREDIENTS

1/2 cup butter, at room temperature
1/4 cup sugar
1 egg, separated
1/2 tsp vanilla
1 cup flour
Pinch sea salt
1/2 cup of your favourite nut (suggestions: almonds, walnuts, hazelnuts, etc.)
1/2 cup of your favourite jam

DIRECTIONS

Cream together butter and sugar at high speed. Add the egg yolk and vanilla and mix in. Add the flour and salt and mix until just combined; don't over mix. Refrigerate the dough for 30 minutes.

Preheat oven to 350 Fahrenheit. If your nuts are raw, toast them to bring out the flavour: Spread the nuts on a baking sheet and bake for about 8 to 10 minutes (about 15 minutes for hazelnuts), until light golden-brown and fragrant. Let cool completely, then process in a food processor until finely chopped, or chop them by hand.

Whisk egg white until bubbly and frothy. Roll the chilled dough into about 1 inch balls. Dip each ball into the egg white then roll it in the chopped nuts. Place on a cookie sheet and press down gently with your thumb to flatten the cookie slightly and make a shallow well. Fill the indentation with about 1/2 teaspoon of jam.

Bake for about 12 to 15 minutes, until slightly brown.

The jam will tend to soften the cookie after a couple of days. To keep them longer or make them easier to freeze, bake them without the jam (reduce the baking time by a few minutes), then just fill the cookies with jam the same day as serving.
