Do I need to thaw ( or partially thaw) frozen gnocchi before boiling?

When they float, they're done.

Thank you. It is homemade. You saved me from disaster!

If homemade? Definitely do NOT thaw. They will go mushy and fall apart. Just use a simmering water method and add a couple more minutes to the cooking time. With Storemade: do not thaw or par-thaw, just cook as directed on pkg and add a 1-2 mins if necessary.
