Hello I'm hoping someone can help me out. I recently purchased the small Chocovision tempering machine for an amazing price. I did a couple test batches and they turned out fine. I do have some newbie questions though about this if someone can help me please. 1. When I place my initial amount in there to melt, say it says it's ready to add seed chocolate, can I wait until the rest of it is melted before I add the seed chocolate? 2. After I add the seed chocolate and it says it's in temper, do I leave the machine running to maintain temper or turn it off and just use the chocolate quickly? 3. If I needed more chocolate, do I have to start the whole process over or is there a way to add more chocolate to the already melted and tempered chocolate? Thanks!
