Cream Ice Cubes
1.
Add egg yolks and sugar and beat until white, add to milk and mix well, boil for a few seconds
2.
After cooling, put it in the refrigerator for 1 hour for later use
3.
Whip the whipped cream with vanilla extract and then add the refrigerated custard, whipping until fluffy, like a cake batter as shown in the figure
