Spread the ricotta onto a short stack of paper towels. Top with several more paper towels and then press down to release as much liquid as possible from the cheese. It should soak into the towels and peel off easily. If it is sticking, it likely still has too much liquid in it - add a few more paper towels and press more.
Weigh the drained cheese and set 8 ounces into a large bowl, reserving any extra cheese for another use. Add almond flour, lupin flour, xanthan gum, glucomann, egg, and egg yolk to the bowl. Season with salt, pepper, and a bit of nutmeg. Stir until completely evenly combined. The dough should form a ball that can be rolled without sticking.
Divide dough into quarters and roll into a ball. Roll each ball into a log that is about 10 inches long and 3/4 inches wide. Cut each log into 8-10 individual gnocchi. You can freeze these on a parchment lined baking sheet and once frozen, transfer to freezer-safe storage (just add 5 minutes to the cooking time) or cook them immediately.
To cook, heat the marinara sauce until barely simmering (I like to simmer this while preparing the gnocchi so it is ready to go as soon as they are cut). Add the gnocchi and cook below a simmer for about 15 minutes, gently turning half way through, or until heated through completely, spooning a bit of sauce over tops of all of them to coat. Do not stir with the sauce as they are a bit fragile. Garnish with more parmesan and some fresh herbs to serve.
