Tips

Tip 1

Make sure sweet potato is completely cool before mixing with flour to prevent gummy texture and ensure proper dough consistency.

Tip 2

Test cook one gnocchi first to check texture - if it falls apart, work more flour into remaining dough before shaping.

Tip 3

Freeze shaped gnocchi on parchment-lined baking sheet before transferring to bags for longer storage.

FAQ

Can I make this without a food processor for the pesto?

Yes, finely mince all ingredients by hand and mix with olive oil, or use a mortar and pestle for better texture than chopping alone.

What if my gnocchi dough is too sticky to shape?

Add more almond flour or arrowroot powder gradually until dough is workable but still soft. Too much flour will make gnocchi tough.

How long will leftover pesto keep in the refrigerator?

Store covered pesto for up to 1 week in refrigerator. Pour thin layer of olive oil on top to prevent oxidation and browning.
