Hi, with the toad in the hole, I part cooked the mini sausage first in the George Forman, then when the oil had warmed up in the pudding tins I placed each sausage in and poured the batter straight over the top, it is a bit fiddly because the pudding tins are so small so if you do have the large 4 hole tins that would be easier. My DMIL is bringing me some 4 hole yorkshire pudding tins from UK when she visits in November.
This recipe actually came from a Jamie Oliver show when I first arrived in Australia and they have never failed. Good luck, hope they work for you because they truly are delicous covered in gravy. My kids can't get enough of them. That batter mix usually makes between 20 - 24 small ones.
