To make a fruit bar, you must first have an amount of ground almonds and pears. Then take 3/4 of the pear and add 1 tablespoon brown sugar to it. After that mix in 2 tablespoons flour then stir over low heat until cooked through.
To make your pastry cream, you need to boil almond milk for about 5 minutes on medium fire before adding one whipped egg yolk with some granulated white sugar so it doesnt curdle into scrambled eggs. Add salt if needed and once the mixture is thick enough pour this into your hot syrup which has been warmed up by bringing water to boiling point on high temperature
