Whip the cream and vanilla seeds to stiff peaks. Slowly add the condensed milk until it is thoroughly combined. Whisk in the egg yolk and mix well. Fold in the chocolate chips. Spoon into a suitable container and freeze overnight.
This is the basic ice-cream recipe so add the relevant ingredients for whichever flavour you want. For example, I like mixing in almond essence with crushed almonds and chopped Peppermint Crisp, or orange essence with orange zest and chocolate chips.
