Thanks for this one! I will do a new batch the weekend and then pour more carefully
If you have sufficient dexterity, you can use an external funnel for pouring. Use one that is fairly large, extends out from the top of the Jobo, so that if you spill or overflow, it ends up outside the tank. But I will say between stripping off the Jobo lid, pouring, putting back on the lid, etc., it takes some practice to do it with - ahem - fluidity.
