This trifle honors Claire's knack for making the best out of available ingredients, much like she does throughout her adventures in a time not her own.
In a trifle bowl, layer half of the pound cake cubes.
Spoon half of the custard over the cake.
Add a layer of berries, then a layer of whipped cream.
Repeat layers with remaining ingredients.
Chill for at least 1 hour before serving.
