Fluffy Tapioca Cream

As someone who's only ever made instant pudding, the idea of using a 20-year-old box of Tapioca mix that requires egg and sugar and vanilla extract to be mixed in should have seemed daunting. By the way, here's the box:

It looks older in-person, not quite as vibrant, and you can see the old-fashioned type as you turn it over.

Anyways, it should have seemed daunting. Everyone was saying I should just use the instant mix, and be done in 5 minutes. But no, I wanted this:

And it tastes like tapioca! I'm hoping that when it cools it's also fluffier. That nice bowl of it was made using just three tablespoons of tapioca mix... so next time I'll use double the ingredients and take pictures of the process. Something tells me I should use up that box.

Oh, and yes, I post here now. There can never be enough food-related internotes.
