For the sweet potato:
Poke holes in the potato with the tip of a knife. Wrap in paper towels, soak and microwave for 5 minutes.
Remove and carefully peel, cut into slices of about 1 finger and cut these slices into 1 finger sticks.
Place in a shape, without overlapping and put on them a thread of olive oil, salt, pepper and paprika. Spread it out well (if you have a cooking brush it helps a lot, otherwise you can use your hands).
Bake in the oven for 15 minutes and it's done.
For the sour cream:
Whip the cream (or almonds), cream cheese, lemon juice, spinach and a pinch of salt and pepper until smooth.
Taste and adjust salt if necessary.
