In a large bowl, cover the fregola with the hot water and soak for 15 minutes. Drain, shaking out the excess water.

Return the fregola to the bowl. Add the pork, shallots, salt, pepper, chopped marjoram, and cinnamon and knead until combined. Transfer the meat mixture to a baking sheet and pat into a 6-by-12-inch rectangle. Cut the rectangle lengthwise into three 2-inch-wide strips and cut each strip into 12 logs.

Snip off the stems at the base of the grape leaves. Smooth out a few leaves on a work surface. Set a log of the filling at the stem end. Roll up the stem end of each leaf once to enclose the filling, then fold in the sides. Tightly roll up the leaves to form a cylinder. Repeat with the remaining grape leaves and filling.

Arrange the stuffed grape leaves in a large, deep skillet in a single layer and scatter the marjoram sprigs on top. Drizzle with the lemon juice and olive oil and pour enough water in the skillet to cover the grape leaves by 1/2 inch. Top with any remaining unfilled grape leaves and a plate to keep the stuffed leaves submerged. Bring to a boil and cover the skillet. Simmer over low heat until the filling is cooked through and the grape leaves are tender, about 1 hour and 30 minutes. Let cool in the liquid.

Drain the stuffed grape leaves, discarding the unstuffed leaves, and transfer to a paper towel-lined plate. Let stand for 30 minutes, then serve warm or at room temperature.

The stuffed grape leaves can be refrigerated for up to 5 days.
