I know several people who love these cookies because they remind them of their childhood. I never had them until I was an adult.
What I especially love about this cookie is the various flavor combinations you come up with just by changing the jam and nuts. For this batch I used almonds and raspberry jam. I'm told this is the traditional flavor. I started thinking about various other flavors I could use.....my imagination went wild and I had to come back down to Earth so I could concentrate on these.
The cookie I made is a combination of several recipes I've tried over the years. I've found this makes and excellent base for the jam. It's not too rich, not too bland. Not too hard, not too soft. Yum.
1/2 teaspoon salt
2 tablespoons milk
2 teaspoons vanilla extract
1 egg white, beaten with about 2 tbsp cool water
I did to about four cookies from this batch with a little Nutella. Super yum and just what I needed.
