Ingredients
Method
Make the dumpling mixture
- Put the bread cubes in a large mixing bowl and pour over the warm milk. Toss and soak for 10 minutes, stirring once, until the cubes are soft with no dry center.
- Rinse the spinach and put it, with the water still clinging to the leaves, in a 28 cm / 6-quart pot. Cover and cook over medium-high heat for 3 to 4 minutes, stirring once, until fully wilted. Tip it into a colander and cool for 5 minutes. Wrap it in a clean kitchen towel and wring hard until no liquid drips and you have roughly 200 g, then chop it finely.
- Melt 1 tablespoon butter in a 30 cm / 12-inch skillet over medium heat. Cook the onion for 4 to 5 minutes, stirring, until soft and translucent but not browned. Let it cool for 2 minutes.
- Add the spinach, onion, eggs, 60 g Trentingrana, 60 g flour, 1 tsp fine salt, nutmeg, and pepper to the soaked bread. Mix with your hands for about 2 minutes, mashing the bread as you go. Squeeze a handful: it should hold a tight, slightly tacky ball. Add 1 tablespoon flour if it sticks wetly to your palm, or 1 tablespoon milk if it crumbles. Cover and refrigerate for 15 minutes.
Cook and finish
- While the mixture rests, rinse the pot, fill it with about 3 liters of water, and add 1 tablespoon coarse salt. Bring to a boil, then reduce to a gentle simmer. Flour your hands and shape the mixture into 12 oval dumplings of about 80 g each, pressing firmly so each one is compact.
- Lower one dumpling in first and watch it for 1 minute: the edges should stay intact. If it sheds, work 1 tablespoon flour into the remaining mixture. Add 5 more dumplings and simmer the batch for 9 minutes, until they float and feel firm when pressed. Lift them out with a slotted spoon onto a warm plate and cover with foil. Repeat with the remaining 6.
- When the second batch has about 3 minutes left, wipe the skillet clean and melt 60 g butter in it over medium heat. Add the sage and cook for about 2 minutes, until the butter foams and smells nutty and the sage turns crisp. Add all 12 dumplings and roll them gently for 1 minute to coat. Divide among warm bowls and top with 30 g grated Trentingrana.
Notes
- Use bread at least a day old, since fresh bread turns gluey once soaked.
- Aim for about 200 g of squeezed spinach, because more water means more flour and denser dumplings.
- Chill the mixture for 15 minutes so the flour hydrates and shaping is easier.
- Cook in two batches of six so the water stays at a gentle simmer.
