My ice cream maker came with several Frozen Custard recipes - here's one -

2 eggs, beaten until fluffy
1 c. sugar
2 Tbsp. flour
1/8 tsp. salt
2 c. half-and-half
2 c. cream
1-1/2 tsp. vanilla

Combine sugar, flour and salt in a saucepan. Put over low heat or in a double boiler, and gradually stir in the half-and-half. Stir constantly with a wooden spoon until sugar dissolves and mixture starts to thicken (about 10-15 mins) Gradually pour a small amount into the eggs (to prevent coagulation), and then add eggs to the mixture. Cook 1 min. more. Remove from heat and chill.
Then add cream and vanilla, and process in the ice cream maker.

Notes in case - half and half is half milk, half cream. Light cream or a mixture of milk and cream would probably do for you if you don't have the exact product.

Thanks I have seen the caters individual portions of half and half in Britain but have not seen half and half as a product in the supermarkets.

I will do as you suggest and make from cream and milk.
