Nigella Lawson's Martini Olives

These are really good, if you like martinis! I don't drink alcohol very often but I always loved the olive in a vodka martini.

4 - 240 gram jars of good quality pimento-stuffed green olives
60 ml gin or vodka
15 ml vermouth
1 teaspoon chili oil

Drain the olives and put them into a large bowl. Add the rest of the ingredients. Let the olives steep for at least 30 minutes before serving. Great for parties (or snacking!).
