I've got a package of Reese small pearl tapioca in front of me, ready to make tapioca pudding, but I forgot to factor in the recommended overnight soak. Is it possible to accelerate the process by soaking in warm or boiling water or by substituting a longer cooking time?
Yes, it works without presoaking. You have to cook them for quite a long time until they become quickly translucent, the small ones will need about 30 minutes at a moderate boil. It is not optimal, as the outside will become mushier in this long cooking time, but there are people who don't mind the difference.
