Next heat, on high heat, 2 tbsp of oil in a large pot until it starts to smoke. Carefully drop the chopped rabe into the pot. Please be careful as you are adding water drops to very hot oil. Of note, depending on the size of pot and the size of your rabe bunches, you may have to add them to the pot in batches. It may splatter as you will be adding wet rabe to hot oil. After about 5 seconds stir the rabe so that what was on the Bottom ends on the top. As it starts to cook, it will reduce in volume. Continue to add the rabe until it is all in the pot.
