Put eggs and egg yolks into a bowl and beat lightly. Slowly whisk a cup of warm cranberry liquid into the eggs to temper, then combine both and whisk together. Wipe out pot if necessary, return liquid to pot and cook over low heat until nearly bubbling and thickened, about 10 minutes. If using immediately, let cool to room temperature. If working ahead, cool to room temperature, cover with plastic wrap (press wrap against curd) and refrigerate. (Curd may be cooked up to 1 day ahead.)
