Pain in the neck. But it does remove a slight bitterness you may not want in your final product.

Skins get stuck in your teeth.

The skins are like bran. They add a lot of grittiness that you probably don't want. It's easy enough. Put hot nuts between two dishtowels and rub them around in a circular motion. Skins will come off.

i eat peanuts with skins

You don't cook certain things with the nuts still having skins. It is very unattractive in the final products ( think about peanut brittle).

We do it because Martha says so. She has her reasons.

The skins usuallly add a bitter aftertaste. Most hazelnuts are used for sweet purposes, cakes and tortes.

Actually, I eat almonds with the skin. So, I guess not all. Still, just trying to figure out why for hazelnuts.

But why?

You do the same for any nut.

Is it just about the way they look, or are the skins bitter or something?
