From LCBO's Food and Drink Magazine. This superb German-inspired tart uses both green and white asparagus, although you could substitute either kind. It looks especially attractive if you lay 2 spears of green then 1 spear white, turning the white so that its head is next to the stem of the green. If the stalks are thick they will need to be peeled - otherwise don't bother. If Taleggio is unavailable, use Gruyère. Cooking time includes resting time for yeast and dough.
