Preheat oven to 350°F. Boil the baby artichokes in acidulated water - water with a little lemon squeezed in until tender. Quarter the artichokes, removing any residual choke, if necessary.
Beat the cream cheese and cream together until smooth. Fold in the artichokes, jalapeño and cheeses.
Transfer mixture to an ovenproof dish. Sprinkle with toasted breadcrumbs and bake for 10 minutes, or until hot and bubbly. Serve with pita chips, sliced baguettes, or your favorite dipping veggies.
