Here is an example using a fresh installation of express v3.0.0rc4

app.js:

app.use(function(req, res, next){
  res.locals.variable = "some content";
  next();
})

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

index.jade:

extends layout

block content
  h1= title
  p Welcome to #{title}
  p= variable
