Making these is so easy and people do kind of swoon over them, so you're sure to win some points when you serve them. Put a bowl out at your next party and watch 'em disappear.
They're also a nice addition to lentil or winter squash soup.
Add one package (16 oz, 1 lb or 454g) of raw, whole chestnuts to a bowl. Drizzle them with just enough olive oil to lightly coat the nuts. Add one tablespoon of finely chopped fresh rosemary (pull the leaves off the woody stem before chopping). Add 1-2 teaspoons of good salt.
Mix it all together.
Spread them out on a baking pan.
Allow them to cool completely, then pack them up in an airtight container.
