Ischler Cookies

For this Christmas, I've written Ischler cookies in my baking list, thinking that I would use the recipe featured here before but then I came across this one from The Eccentric Cook . Hers look absolutely scrumptious, so I thought "why not give it a try?".
These turned out crumbly and nutty, just the way I (or we) like it! Since these cookies are better the longer you keep them, you could bake them few days before serving. Just keep in an air-tight container and store in a cool place.

Ingredients

200 grams flour

100 grams ground walnut or almond meal

1/2 tsp salt

150 grams butter

50 grams sugar

1 lemon's zest

1 Tbsp rum

for the filling

fruit preserve of your choice

for the chocolate coat

180 grams chocolate

2 Tbsp oil

Process

For the linzer cookie dough, mix the flour, ground walnut, salt and sugar together. Cut the butter in it. Add in the lemon zest and the rum. You can use an electric mixer but I found that after a while you should switch to working with your hands. The dough will be very crumbly but after 5 minutes it will come together. Form the dough into a ball and chill in the fridge for 30 minutes.

Dust a bread board or your counter with flour and roll the dough into about 1/2 cm. I didn't really know how thick 1/2 cm is in a dough form so I just trusted my eyes. It should look like this:

The dough will be very sticky so it will be a bit tricky to roll it out but sprinkle some flour on it and you'll be fine. It's essential for the dough to be this sticky, that's why it will have the perfect crumble to it. 

Preheat your oven to 170C or 350F.

Cut rounds in the dough with a cutter. My cutter was too small so I just used a glass :)

Once you cut all the holes, collect the remaining dough and roll it out again and cut the rounds the same way.

Place the cookies on a baking sheet and bake them for 12-13 minutes. They should have a very light color, don't wait until they brown because it will dry the cookies.

Chill the cookies for 10 minutes. Then take one cookie and spread a fruit preserve of your choice on it lightly.

Press the other side of the cookie on the preserve and repeat the same method with all the other cookies.

When you're done, melt the chocolate and oil over boiling water. Place the cookies on a cooling rack. Put a baking sheet or foil under it. Then pour the chocolate over the cookies.

The chocolate will need time to harden so it's advised not to touch for a couple of hours. Decorate the cookies with an almond or walnut on top! The cookies taste better after time so if you make this for a gathering, make it 1 day prior!
