These are great!
Steaming in the varoma is an excellent option to boiling them (even if you use a different recipe I urge you to try steaming instead of boiling). I was able to steam 7 at a time..I'll be making these again for sure!
Tweaks: At the end of the kneading time stated in the recipe, I wasn't happy with the mix (dryish and in smallish balls), so I added 30g of water extra and kneaded for an additional 2-3 minutes until the dough 'looked right'.
Next time I'll also make the hole much bigger, I wasn't expecting them to rise so much during the steaming time.
