That's the best looking cooked rhubarb I've ever seen Katie.
That is not such a hot oven BZB. Yikes how do you manage? Well, rev it up as high as. Just will take longer. You can cut it before just as easily or after. I think I did it before on the one in the pic. I like the crust brown and crispy on the bottom to avoid sog.With an oven like that it might pay to par bake the crust before adding the toppings and popping it back in. Yes I think I would do that so the topping does not over cook.Let me know how it goes.You could always use a satay sauce or curry sauce for the base to make a spicy beef or chicken. Yum.Gert
