This one is for the culinarily challenged or those whose memory does not serve that well. All you need to remember is this:
To be exact, you need
- 200 grams (8 oz) walnuts (you can throw in a few hazelnuts if you want)
- 200 grams (8 oz) powdered sugar
- egg whites from 4 eggs
Make sure to shred/grate the nuts in a cheese grater or a food processor first. I use my old school German "reibemachine". You also need a double-walled pot. If you don't have a double-walled pot, you can use a regular pot (put about an inch of water at the bottom) with a glass or metal bowl over it. Using this kind of pot will prevent the ingredients from burning.
Wait few minutes until the pot is hot, then add egg whites with sugar and keep whisking for few minutes until bubbles form. Add the nuts and whisk a bit more until well combined.
Scoop the dough onto a non-stick sheet, top with hazelnuts, and bake on a low temperature (265 F) for about 20-30 minutes until the bottoms of the cookies start getting crusty. You are really just drying them up to a desired consistency. You might like them chewy or crunchy. It's up to you.
Share them with friends or keep them all to yourself. I shared mine with a co-worker who took a code compilation monitoring shift for me while I was on vacation.
Enjoy!
