no pictures sorry, a one hour long tantrum by the 5 year old ensured that, but here is a bit of a method for this. i may need to edit it next time as i'm not sure my brain was really focusing on gnocchi :(
for 4-6 people
350g Sweet potato, peeled and cubed
650g desiree potatoes, peeled and cubed
2+ cups flour
salt & pepper
steam the potatoes & sweet potatoes. i did mine in the microwave but of course you could do it in the varoma if you wanted and didn't have your mind on when the noise was going to stop...
(you would probably use about 500g water, 12-15 mins (??) varoma temp, speed 2
they need to be really soft but not falling apart.
drain them well and let them cool as much as you can (last time i kept them in teh fridge overnight and this worked well.
put about 500g in the tmx and chop til they're fine - but be careful! you don't want to make glue out of them! (have done that before with a food processor, NOT pretty!) i did speed 6 for about 30-40 seconds i think.
remove to another bowl and repeat. add the first batch back in and add the other ingredients.
mix on speed 6 until well mixed, again keep an eye out for gluey tendencies! i was very distracted by the 5yo at this stage and mine was done for 2 minutes and was OK thank goodness, so glue must be less likely at this stage ;p
put a large pot of water on to boil.
remove from tmx and place on a floured surface. knead until smooth, adding extra flour until the dough is no longer sticky. my dough was very sticky at this stage (i think the sweet potatoes have more water than regular potatoes) so i had to add a LOT of extra flour, but it was fine in the end.
cut the dough into 4-6 pieces and then take one. roll out on the floured surface until you have a sausage that is about 2cm thick. cut into 1cm pieces with a knife (i used a bread knife so i didn't cut my silicone mat). i actually just cook them like that because we don't care what they look like!
but if you want them to look pretty like "real" gnocchi just roll them a little into a ball then press into shape with a fork.
to cook them you need boiling water - just drop one sausage worth of gnocchi in at a time (i found it took the exact time to make the next sausage-worth as it did to cook each batch of gnocchi). they are cooked when they flat on the surface - use a large flat slotted spoon to remove & drain them. you can serve them straight into a bowl.
top with sauce and cheese as desired.
of course you can swap the sweet potato for pumpkin, or use more potato and a little black olives etc etc - the options are endless!
