should rhubarb be thawed before using it to bake with
The ideal solution, of course, is to grow your own but if that is not possible, then you can use the frozen chopped unsweetened rhubarb that is sold in 1 pound (454 grams) bags. If you use frozen rhubarb you do not have to thaw the rhubarb before baking, although the baking time may have to be extended a bit.nce the rhubarb is soft, remove from oven and drain in a strainer suspended over a bowl. Press the rhubarb to force out the juice. There should be about 1/2 - 2/3 cup (120 - 160 ml) of juice.
