One thing I would like to point out is to always whisk each part of this recipe when on the stove, whether it is to prevent burning the milk or curdling the eggs. Another thing I would like to point out is that the final product has a steel grey color. This occurs when the purple from the mulberry mixes with the yellow of the egg yolks. You can use this pastry cream like a Swiss army knife in the kitchen. Use it to fill eclairs or cream puffs, or as a filling in a tart. It's great on crackers or with cream cheese, and especially delicious layered in a pavlova. Enjoy!
