@Katie Meadow I have seen her recipe for melting potatoes but haven’t made them, yet - I make fondant potatoes, though - I have some vague memory(?) they are a sort of shortcut version ??? (Sounds like it from your description) ...
One of my best friends made me (ha!) boil some baby golds in ham or chicken stock or beef stock (whatever) ‘til just soft - remove from stock - put in baking pan - mash them down - drizzle with butter / garlic / olive oil - sprinkle some pepper - bake at 350 til crispy and brown - oy vey! Mr Cat and Cat Son loves those, too! (obviously, we are not watching our carbs 😂) ... add bacon 😁 ...
