In a 12 cups (3 litres) glass serving bowl, assemble the trifle by layering half of each of the preparations except for the caramel that will be divided into 4: pastry cream, lady fingers, pears, caramel and whipped cream. Repeat with the remaining halves and finish with rosettes of whip cream, ¼ of the caramel and almonds. Use the remaining of the caramel for serving.
